VCC Pin Protection Function This IC has the internal protection functions at the VCC pin. 1) Under voltage protection function: VCC UVLO (Under Voltage Lockout) 2) Over voltage protection function: VCC OVP (Over Voltage Protection) 3) VCC charge function The VCC charge function charges the VCC pin from the high voltage line through the starter circuit at startup time and so on. (1) VCC UVLO / VCC OVP Function VCC UVLO function and VCC OVP function are auto recovery type protection function with voltage hysteresis. Switching is stopped by the VCC OVP function when the VCC pin voltage≥VOVP1A (Typ=32.0 V) or the VCC pin voltage≥VOVP1B (Typ=27.5 V), and restarts when the VCC pin voltage≤VOVP2A (Typ=24.0 V) or the VCC pin voltage≤VOVP2B (Typ=23.5 V).

D: When the VCC pin voltage is VCHG2 (Typ=15.0 V) or more, the VCC charge function stops. E: When the status that the VCC pin voltage is VOVP1A (Typ=32.0 V) or VOVP1B (Typ=27.5 V) or more continues for tCOMP1 (Typ=100 μs), switching is stopped by the VCC OVP function. F: When the VCC pin voltage becomes VOVP2A (Typ=24.0 V) or VOVP2B (Typ=23.5 V) or less, switching operation restarts. G: The VCC pin voltage drops. H: Same as C. I: Same as D. J: When the input voltage VH drops and the VCC pin voltage becomes VUVLO2 (Typ=10.2 V) or less, switching operation is stopped by the VCC UVLO function. (2) VCC Charge Function The IC starts to operate when the VCC pin voltage becomes VUVLO1 (Typ=15.5 V) or more. After that, the VCC charge function operates when the VCC pin voltage becomes VCHG1 (Typ=10.7 V) or less. During this time, the VCC pin is charged from the DRAIN pin through the starter circuit. By this operation, failure at startup is prevented. Once the VCC charge function starts, it continues charge operation until the VCC pin voltage becomes VCHG2 (Typ=15.0 V) or more, after which the charge function stops. www.rohm.com © 2018 ROHM Co., Ltd.

DC/DC Driver (PWM Comparator, Frequency Hopping, Slope Compensate, OSC, Burst) This IC operates by current mode PWM control. The internal oscillator sets the switching frequency at a fixed value when the FB pin voltage ≥ VDLT1 (Typ=1.25 V). It also has a built-in switching frequency hopping function. Maximum duty cycle is fixed at 75 % (Typ) and minimum pulse width is fixed at 500 ns (Typ). With current mode control, when the duty cycle exceeds 50 %, a sub harmonic oscillation may occur. As a countermeasure, the IC has built-in slope compensation function. This IC also has a built-in burst mode operation and frequency reduction operation to achieve lower power consumption in light load. The FB pin is pulled up by RFB (Typ=30 kΩ) to an internal regulator. The FB pin voltage varies with secondary output voltage (secondary power). Burst mode operation and frequency reduction operation is determined by monitoring the FB pin voltage. (1) Frequency Reduction Circuit Figure 5A to Figure5C shows the FB pin voltage, switching frequency, and DC/DC operation modes. mode 1: Burst voltage has hysteresis. Switching stops when the FB pin voltage ≤ VBST1 (Typ=0.4 V), and restarts when the FB pin voltage ≥ VBST2 (Typ=0.45 V). mode 2: When the FB pin voltage ≤ VDLT2 (Typ=0.65 V), switching frequency is at fSW2 (Typ=25 kHz, 27 kHz or 35 kHz). At VDLT2 < the FB pin voltage ≤ VDLT1, switching frequency changes within the range of fSW1 to fSW2. mode 3: Operates in fixed frequency fSW1 (Typ=65 kHz, 100 kHz or 130 kHz). mode 4: If the IC detects over load status within a period of tFOLP1 (Typ=64 ms), it stops switching operation for tFOLP2 (Typ=512 ms).

DC/DC Driver – continued (3) Over Current Limiter This IC has a built-in over current limiter per cycle. When the SOURCE pin voltage becomes VCSA (Typ=0.4 V) or VCSB (Typ=0.3 V) or more for 1 pulse, switching is turned off after passing internal delay time. The delay time varies in relation to the time by which the SOURCE pin voltage reaches VCSA (Typ=0.4 V) or VCSB (Typ=0.3 V). By this time, AC voltage correction function operates. The relations of the time until the SOURCE pin voltage reaches V CSA (Typ=0.4 V) or VCSB (Typ=0.3 V) and the additional delay time are shown in below. Figure 6A. Delay Time vs the Time by Which the SOURCE Pin Voltage Reaches VCSA (Typ=0.4 V) (BM2P061FK-LBZ) Figure 6B. Delay Time vs the Time by Which the SOURCE Pin Voltage Reaches VCSB (Typ=0.3 V) (BM2P101FK-LBZ) Figure 6C. Delay Time vs the Time by Which the SOURCE pin Voltage Reaches VCSB (Typ=0.3 V) (BM2P131FK-LBZ) Ip is calculated by the following formula. 𝐼𝑝 = 𝑉𝑖𝑛 𝐿𝑝 × (𝑡𝑂𝑁 + 𝑡𝐷 + 𝑡𝐷𝐸𝐿𝐴𝑌 ) [A] where: 𝑉𝑖𝑛 is the AC Input Voltage. 𝐿𝑝 is the Primary Inductance. 𝑡𝑂𝑁 is the Time to VCSA or VCSB. 𝑡𝐷 is the Additional Delay Time introduced by the IC (Refer to Figure 6A to Figure 6C). 𝑡𝐷𝐸𝐿𝐴𝑌 is the Delay Time peculiar to the IC (Typ=0.2 μs). About the above Figure 6A to Figure 6C, design application considering that tD operates in the range of ±20 % and tDELAY operates in the range of ±0.1 µs. It is necessary to evaluate application in the end and adjust sense resistor and so on. www.rohm.com © 2018 ROHM Co., Ltd. All rights reserved.

State Transition of Switching Frequency (5) Soft Start Function This function controls the over current limiter value in order to prevent any excessive rise in voltage or current upon startup. Figure 8 shows the details of soft start function. The IC implements soft start function by changing the over current limiter value with time.

Time When MOSFET is turned ON, surge current occurs by capacitive elements and drive current. During this time, there is a probability of detection error in the over current limiter circuit due to a rise in the SOURCE pin voltage. To prevent it, there is a built-in L.E.B. function (Leading Edge Blanking function) to mask the SOURCE pin voltage for tLEB (Typ=250 ns) after turn ON. www.rohm.com © 2018 ROHM Co., Ltd.

SOURCE Pin Short Protection When the SOURCE pin is shorted to ground, the IC may overheat and get destroyed. To prevent destruction, it has a built-in short protection function. Switching is turned off in tCSSHT (Typ=2.0 µs) ON width when the status that the SOURCE pin voltage is VCSSHT (Typ=0.06 V) or less is detected by this function. 6. Output Over Load Protection Function (FB OLP Comparator) Output over load protection function monitors the load condition and stops switching operation when over load condition is detected. The IC detects over load status at the FB pin voltage ≥ VFOLP1 (Typ=3.4 V) and releases FB OLP at the FB pin voltage ≤ VFOLP2 (Typ=3.2 V). As output voltage decreases during over load condition and this condition continues for tFOLP1 (Typ=64 ms), over load condition is detected and switching operation stops. FB OLP detection will be released after the auto-recovery period tFOLP2 (Typ=512 ms). 7. Input Voltage Protection Function (Brown IN/OUT) This IC has a built-in UVLO function that monitors the input voltage through the BR pin. It prevents the IC from heating by over-current when the input voltage is low. When BR UVLO function is released, IC operates by soft start. The BR pin capacitor must be connected to prevent malfunction. e.g. The case that BR UVLO is released when the input voltage is 130 Vac. 130𝑉×√2×𝑅𝐵𝑅2 𝑅𝐵𝑅1 +𝑅𝐵𝑅2 = 𝑉𝐵𝑅1 [V] When RBR1 is set to 1.23 MΩ, RBR2 is calculated to 4.7 kΩ. Then, BR UVLO voltage is calculated as: (𝑅𝐵𝑅1 +𝑅𝐵𝑅2 )×𝑉𝐵𝑅2 𝑅𝐵𝑅2 ×√2 = 71 [Vac] Therefore, the hysteresis is 59 Vac.

Then internal timer starts to operate because of detection of the three times continuation. After tZTOVP (Typ=100 µs) from the three times detection, the IC stops by latch.

The ZT pin voltage ≥ VZTOVP (Typ=3.5 V) Because the ZT pin voltage ≥ VZTOVP (Typ=3.5 V) status continues for tZTOVP (Typ=100 µs), latching occurs and DC/DC is turned OFF. www.rohm.com © 2018 ROHM Co., Ltd.

The damage can either be a short circuit between pins or an open circuit between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute maximum ratings. Caution 2: Should by any chance the maximum junction temperature rating be exceeded the rise in temperature of the chip may result in deterioration of the properties of the chip. In case of exceeding this absolute maximum rating, design a PCB with power dissipation taken into consideration by increasing board size and copper area so as not to exceed the maximum junction temperature rating. (Note 1) Reduce by 8.0 mW/°C when operating Ta=25 °C or more when mounted on 70 mm x 70 mm x 1.6 mm thick, glass epoxy on single-layer substrate. Thermal Loss The thermal design should set operation for the following conditions. 1. The ambient temperature Ta must be 105 °C or less. 2. The IC’s loss must be within the power dissipation Pd. The thermal reduction characteristics are as follows. (PCB: 70 mm x 70 mm x 1.6 mm mounted on glass epoxy single layer substrate) Figure 13.
