High Performance Regulators for PCs Nch FET Ultra LDO for PC Chipsets BD3506F,BD3506EFV No.10030EAT30 Description The BD3506F/EFV is an ultra-low dropout linear regulator for chipset that can achieve ultra-low voltage input to ultra-low voltage output. By using N-MOS FET for built-in power transistor, the regulator can be used at ultra-low I/O voltage difference up to voltage difference generated by ON resistor (Ron = 120 mΩ/100 mΩ). Because by reducing the I/O voltage difference, large current (Iomax = 2.5A) output is achieved and conversion loss can be reduced, switching power supply can be replaced. BD3506F/EFV does not need any choke coil, diode for rectification and power transistors which are required for switching power supply, total cost of the set can be reduced and compact size can be achieved for the set. Using external resistors, optional output from 0.65V to 2.5V can be set. In addition, since voltage output start-up time can be adjusted by using the NRCS terminal, it is possible to meet the power supply sequence of the set. Features 1) Built-in high-accuracy reference voltage circuit (0.65V±1%) 2) Built-in VCC low input maloperation prevention circuit (Vcc = 4.15V) 3) Reduced rush current by NRCS 4) Built-in ultra-low on-resistor (120/100 mΩ typ) Nch Power MOSFET (BD3506F/BD3506EFV) 5) Built-in current limiting circuit (2.5A min) 6) Built-in thermal shutdown circuit 7) Output variable type (0.65-2.5V) 8) Adoption of SOP8 package (BD3506F): 5.0 x 6.2 x 1.5 (mm) 9) Adoption of high power HTSSOP-B20 package (BD3506EFV): 5.0 x 6.4 x 1.0 (mm) Applications Mobile PC, desktop PC, LCD-TV, DVD, digital home appliances ●Line up Parameter Ron Output Current Package BD3506F 120mΩ 2.5A SOP8 BD3506EFV 100mΩ 2.5A HTSSOP-B20 ●Absolute Maximum Ratings(Ta=25℃) Parameter Input Voltage1 Input Voltage2 Enable Input Voltage Power Dissipation1 Power Dissipation2 Operating Temperature Range Storage Temperature Range Maximum Junction Temperature Symbol VCC VIN Ven Pd1 Pd2 Topr Tstg Tjmax Ratings BD3506F 7 *1 7* 7 560 *2 690 *3 -10～+100 -55～+125 +150 1 BD3506EFV 7 *1 7* 7 1000 *4 -10～+100 -55～+125 +150 1 Unit V V V mW mW ℃ ℃ ℃ *1 However, not exceeding Pd. *2 In the case of Ta≥25°C (no heat radiation board), derated at 4.48 mW/°C. *3 In the case of Ta≥25°C (when mounting to 70mmx70mmx1.6mm glass epoxy substrate), derated at 5.52 mW/°C. *4 In the case of Ta≥25°C (when mounting to 70mmx70mmx1.6mm glass epoxy substrate), derated at 8.00 mW/°C. www.rohm.com © 2010 ROHM Co., Ltd.

The frequency characteristics are optimized so that low ESR functional polymer capacitor can be used for the output capacitor and high-speed transient response can be achieved. The input voltage range at the AMP section is GND-2.5V and the output voltage range of the AMP section is GND-VCC. At the time of EN OFF or UVLO, the output is brought to the LOW level and the output NchFET is turned OFF. EN By the logic input pin, regulator ON/OFF is controlled. At the time of OFF, the circuit current is controlled to be 0 µA to reduce the standby current consumption of the apparatus. In addition, EN turns ON FET that can discharge NRCS terminal Vo and removes excess electric charge to prevent maloperation of IC on the load side. Since there is no electrical connection with the Vcc terminal as is the case of Di for electrostatic measures, it does not depend on the input sequence. UVLO UVLO turned OFF output to prevent output voltage from making maloperation at the time of Vcc reduced voltage. Same as EN, UVLO discharges NRCS Vo. When voltage exceeds the threshold voltage (TYP 4.15V), UVLO starts output. CURRENT LIMIT In the event the output current that exceeds the current (2.5A or more) set inside the IC flows when output is turned ON, output voltage is attenuated to protect the IC on the load side. When current reduces, output voltage returns to the set voltage. NRCS Connecting an external capacitor to the counter-GND of NRCS pin can achieve soft start. The output voltage startup time is determined by the time when the NRCS terminal reaches VFB (0.65V). During start-up, the NRCS terminal serves as a constant current source of 20 µA (Typ.) output, and charges the capacitor externally connected. TSD (Thermal Shut down) In order to prevent thermal breakdown and thermal runaway of the IC, the output is turned OFF when chip temperature becomes high. In addition, when temperature returns to the specified temperature, the output is recovered. However, since the temperature protection circuit is originally built in to protect the IC itself, thermal design within Tj(max) is requested. VIN This is a large-current supply line. The VIN terminal is connected to the rain of output NchFET. Since there is no electrical connection with the Vcc terminal as is the case of Di for electrostatic measures, it does not depend on the input sequence. However, because there is body Di of output NchFET between VIN and Vo, there is electrical connection (Di-connection) between VIN and Vo. Consequently, when the output is turned ON/OFF by VIN, reverse current flows from Vo to VIN, to which care must be taken. www.rohm.com © 2010 ROHM Co., Ltd.

Output voltage can be set by VRxR2/(R1+R2) but it is recommended to 6.5k/5.5k use at the resistance value (total: about 10 kΩ) which is not susceptible to VREF bias current (±100 nA). C3 100µF Connect the output capacitor between Vo1, Vo2 terminals and GND terminal without fail in order to stabilize output voltage. The output capacitor has a role to compensate for the phase of loop gain and to reduce output voltage fluctuation when load is rapidly changed. When there is an insufficient capacity value, there is a possibility to cause oscillation, and when the equivalent serial resistance (ESR) of the capacitors is large, output voltage fluctuation is increased when load is rapidly changed. About 100-µF high-performance electrolytic capacitors are recommended but output capacitor greatly depends on temperature and load conditions. In addition, when only ceramic capacitors with low ESR are used, or various capacitors are connected in series, the total phase allowance of loop gain becomes not sufficient, and oscillation may result. Thoroughgoing confirmation at application temperature and under load range conditions is requested. The input capacitor plays a part to lower output impedance of a power supply connected to input terminals (Vcc). When output impedance of this power supply increases, the input voltages (Vcc,) become unstable and there is a possibility of giving rise to oscillation and degraded ripple rejection characteristics. The use of capacitors of about 0.1 µF with low ESR, which provide less capacity value changes caused by temperature changes, is recommended, but since input capacitor greatly depends on characteristics of the power supply used for input, substrate wiring pattern, thoroughgoing confirmation under the application temperature and load range, is requested. The input capacitor plays a part to lower output impedance of a power supply connected to input terminals (VIN). When output impedance of this power supply increases, the input voltages (VIN) become unstable and there is a possibility of giving rise to oscillation and degraded ripple rejection characteristics. The use of capacitors of about 10 µF with low ESR, which provide less capacity value changes caused by temperature changes, is recommended, but since input capacitor greatly depends on characteristics of the power supply used for input, substrate wiring pattern, thoroughgoing confirmation under the application temperature and load range, is requested. To the present IC, there mounted is a function (Non Rush Current on Start-up: NRCS) to prevent rush current from VIN to load and output capacitor via Vo at the output voltage start-up. When the EN terminal is reset from High or UVLO, constant current is allowed to flow from the NRCS terminal. By this current, voltage generated at the NRCS terminal becomes the reference voltage and output voltage is started. In order to stabilize the NRCS set time, it is recommended to use a capacitor (B special) with less capacity value change caused by temperature change.

(Because the following temperatures are warranted temperature, be sure to take margin, etc. into account.) 1. Ambient temperature Ta shall be not more than 100°C. 2. Chip junction temperature Tj shall be not more than 150°C. Chip junction temperature Tj can be considered under the following two cases. ①Chip junction temperature Tj is found from IC surface temperature TC under actual application conditions: Tj=TC+θj-c×W ＜Reference value＞ θj-c:SOP8 41.0℃/W HTSSOP-B20 45.0℃/W Substrate size:70×70×1.6mm (Substrate surface capper foil area:less3%) θj-a:HTSSOP-B20 125.0℃/W 86.2℃/W 54.3℃/W 39.1℃/W ②Chip junction temperature Tj is found from ambient temperature Ta: Tj=Ta+θj-a×W ＜Reference value＞ θj-a:SOP8 222.0℃/W (IC only) 181.0℃/W Single-layer substrate (substrate surface copper foil area: less 3%) Single-layer substrate θj-a:HTSSOP-B20 125.0℃/W (substrate surface copper foil area: less 3%)) 2nd-layer 2 86.2℃/W (substrate surface copper foil area:15×15mm ) 2nd-layer 2 54.3℃/W (substrate surface copper foil area: 70×70mm ) 4th-layer 2 39.1℃/W (substrate surface copper foil area: 70×70mm ) 3 Substrate size 70×70×1.6mm (thermal vias in the board.) Most of heat loss in BD3506F/EFV occurs at the output Nch FET. The power lost is determined by multiplying the voltage between VIN and Vo by the output current. Confirm voltage and output current conditions of VIN and Vo used, and collate them with the thermal derating characteristics. Because BD3506EFV employs the power PKG, the thermal derating characteristics significantly vary in accord with the pc board conditions. When designing, care must be taken to the size of a pc board to be used. Power dissipation (W) = {Input voltage (VIN) – Output voltage (V0≒VREF)}×Io (averaged) Ex.) If VIN = 1.8 volts, V0=1.2 volts, and Io (averaged)=1.5 A, the power dissipation is given by the following: Power dissipation (W) =(1.8 volts – 1.2 volts) × 1.5 (A) = 0.9 W ●Equivalent Circuit Vcc Vcc NRCS 1kΩ 1kΩ 1kΩ 1kΩ VIN 1kΩ 10kΩ 10kΩ 1kΩ Vcc Vcc 1kΩ Vo1 Vo2 50kΩ 1kΩ VFB 1kΩ 100kΩ 100kΩ EN 350kΩ 20pF 10kΩ www.rohm.com © 2010 ROHM Co., Ltd.

Input terminals (VCC,VIN,EN) In the present IC, EN terminal, VIN terminal, and VCC terminal have an independent construction. In addition, in order to prevent malfunction at the time of low input, the UVLO function is equipped with the VCC terminal. They begin to start output voltage when all the terminals reach threshold voltage without depending on the input order of input terminals. 2. Operating range Within the operating range, the operation and function of the circuits are generally guaranteed at an ambient temperature within the range specified. The values specified for electrical characteristics may not be guaranteed, but drastic change may not occur to such characteristics within the operating range. 3. Permissible dissipation With respect to the permissible dissipation, the thermal derating characteristics are shown in the Exhibit, which we hope would be used as a good-rule-of-thumb. Should the IC be used in such a manner to exceed the permissible dissipation, reduction of current capacity due to chip temperature rise, and other degraded properties inherent to the IC would result. You are strongly urged to use the IC within the permissible dissipation. 4. Built-in thermal shutdown protection circuit The thermal shutdown circuit is first and foremost intended for interrupt IC from thermal runaway, and is not intended to protect and warrant the IC. Consequently, never attempt to continuously use the IC after this circuit is activated or to use the circuit with the activation of the circuit premised. 5. Inspection by set substrate In the event a capacitor is connected to a pin with low impedance at the time of inspection with a set substrate, there is a fear of applying stress to the IC. Therefore, be sure to discharge electricity for every process. As electrostatic measures, provide grounding in the assembly process, and take utmost care in transportation and storage. Furthermore, when the set substrate is connected to a jig in the inspection process, be sure to turn OFF power supply to connect the jig and be sure to turn OFF power supply to remove the jig. 6. For the present product, thoroughgoing quality control is carried out, but in the event that applied voltage, working temperature range, and other absolute maximum rating are exceeded, the present product may be destroyed. Because it is unable to identify the short mode, open mode, etc., if any special mode is assumed, which exceeds the absolute maximum rating, physical safety measures are requested to be taken, such as fuses, etc.. 7. The use in the strong electromagnetic field may sometimes cause malfunction, to which care must be taken. 8. In the event that load containing a large inductance component is connected to the output terminal, and generation of back-EMF at the start-up and when output is turned OFF is assumed, it is requested to insert a protection diode. (Example) OUTPUT PIN 9. We are certain that examples of applied circuit diagrams are recommendable, but you are requested to thoroughly confirm the characteristics before using the IC. In addition, when the IC is used with the external circuit changed, decide the IC with sufficient margin provided while consideration is being given not only to static characteristics but also variations of external parts and our IC including transient characteristics. www.rohm.com © 2010 ROHM Co., Ltd.

With this P layer and N layer of each element, PN junction is formed, and various parasitic elements are formed. For example, when resistors and transistors are connected to terminals as illustrated below, ○at the resistor, when GND>terminal A, and at transistor (NPN), when GND>terminal B,PN junction works as a parasitic diode. ○at the transistor (NPN), when GND>terminal B,the parasitic NPN transistor is operated by the N-layer of other element adjacent to the parasitic diode. The parasitic element is inevitably formed because of the IC construction. The operation of the parasitic element gives rise to mutual interference between circuits and results in malfunction, and eventually, breakdown. Consequently, take utmost care not to use the IC to operate the parasitic element such as applying voltage lower than GND (P substrate) to the input terminal.
