XC9128/XC9129 series is Discontinued. XC9128/XC9129 Series ETR0411-013 1A Driver Transistor Built-In, Step-Up DC/DC Converters ☆Green Operation Compatible ■GENERAL DESCRIPTION The XC9128/XC9129 series are synchronous step-up DC/DC converters with a 0.2Ω (TYP.) N-channel driver transistor and a synchronous 0.2Ω (TYP.) P-channel switching transistor built-in. A highly efficient and stable current can be supplied up to 1.0A by reducing ON resistance of the built-in transistors. With a high switching frequency of 1.2MHz, a small inductor is selectable making the series ideally suited for applications requiring low profile or space saving solutions. With the MODE pin, the series provides mode selection of PWM control or PFM/PWM automatic switching control. In the PWM/PFM automatic switching mode, the series switches from PWM to PFM to reduce switching loss when load current is small. When load current is large, the series switches automatically to the PWM mode so that high efficiency is achievable over a wide range of load conditions. The series also provides small output ripple from light to large loads by using the built-in circuit which enables the smooth transition between PWM and PFM. With a adaptor enable function of the XC9128 series, when a voltage higher than the input voltage is applied to the output, the input and the output become isolated making it possible for the IC to work in parallel with the likes of an AC adaptor. ■ FEATURES ■APPLICATIONS ●Digital audio equipment High Efficiency, Large Current Step-Up Converter : 150mA＠VOUT=3.3V, VIN=0.9V Output Current 500mA＠VOUT=3.3V, VIN=1.8V Input Voltage Range : 0.8V ~ 6.0V : 1.8V ~ 5.3V (Externally set) Output Voltage Setting Set up freely with a reference voltage Range supply of 0.45V (±0.010V) & external components : 1.2MHz Oscillation Frequency (Fixed oscillation frequency accuracy ±15%) Input Current : 1.0A Maximum Current Limit : 1.2A (MIN.), 2.0A (MAX.) ●Digital still cameras / Camcorders ●Computer Mouses ●Multi-function power supplies : PWM, PWM/PFM control externally selectable High Speed :100mV @ VOUT=3.3V, Transient Response VIN=1.8V, IOUT=10mA→100mA : Thermal shutdown Protection Circuits Integral latch method (Over current limit) Soft-Start Time : 5ms (TYP.) internally set Ceramic Capacitor Compatible Adaptor Enable Function (XC9128 series) Flag Output (XC9128 series) : Open-drain output Operating Ambient Temperature : - 40 ~ 85℃ Packages : MSOP-10, USP-10B Environmentally Friendly : EU RoHS Compliant, Pb Free Control ■TYPICAL PERFORMANCE CHARACTERISTICS ■TYPICAL APPLICATION CIRCUIT ●Efficiency vs. Output Current XC9128B45CD VOUT 10 2 Lx MODE 9 3 BAT FB 8 4 EN MODE VIN L EN FO 5 FO AGND AEN/ 100 VOUT PGND 1 90 CFB RFB1 7 6 RFB2 CL (ceramic) Efficiency: EFFI (%) CIN L=4.7μH(LTF5022-LC),CL =30μF(LMK212BJ106KG ×3) VOUT=3.3V,VEN=6V,VFO =OPEN,VAEN/ =0V RFB1 =270kΩ,RFB2 =43kΩ,CFB=12pF,CIN=10μF 80 70 1.8V 60 3.0V 50 40 30 20 PWM/PFM (VMODE=0V) PWM (VMODE=VOUT) 10 0 0.1 1 10 100 1000 Output Current: I OUT (mA) 1/28 XC9128/XC9129 series is Discontinued.

Output voltage is determined by the following equation, based on the values of RFB1 and RFB2. The sum of RFB1 and RFB2 should normally be 500kΩ or less. VOUT=0.45 × (RFB1 + RFB2) / RFB2 The value of CFB, speed-up capacitor for phase compensation, should be fZFB = 1 / (2 x π x CFB1 x RFB1) which is in the range of 10 kHz to 60 kHz. Adjustments are depending on application, inductance (L), load capacitance (CL) and dropout voltage.

Capacitance CL1 + CL2 is recommended 30μF or higher. (Ceramic capacitor compatible) If CL1 is lower than 10μF, operation may be unstable. In case of the usage CL1 + CL2 ＜30μF, output ripple may increase so that we recommend that you fully check actual performance on the board. * If using Tantalum or Electrolytic capacitors please be aware that ripple voltage will be higher due to the larger ESR (Equivalent Series Resistance) values of those types of capacitors. Please also note that the IC’s operation may become unstable with such capacitors so we recommend that you fully check actual performance. 9/28 XC9128/XC9129 series is Discontinued. XC9128/XC9129 Series ■OPERATIONAL EXPLANATION The XC9128/XC9129 series consists of a reference voltage source, ramp wave circuit, error amplifier, PWM comparator, phase compensation circuit, N-channel driver transistor, P-channel synchronous rectification switching transistor and current limiter circuit. The error amplifier compares the internal reference voltage with the FB pin feed back voltage via resistors RFB1 and RFB2. Phase compensation is performed on the resulting error amplifier output, to input a signal to the PWM comparator to determine the turn-on time of the N-channel driver transistor during PWM operation. The PWM comparator compares, in terms of voltage level, the signal from the error amplifier with the ramp wave from the ramp wave circuit, and delivers the resulting output to the buffer driver circuit to cause the Lx pin to output a switching duty cycle. This process is continuously performed to ensure stable output voltage. The current feedback circuit monitors the N-channel driver transistor’s turn-on current for each switching operation, and modulates the error amplifier output signal to provide multiple feedback signals. This enables a stable feedback loop even when a low ESR capacitor, such as a ceramic capacitor, is used, ensuring stable output voltage. The source provides the reference voltage to ensure stable output of the DC/DC converter. The ramp wave circuit determines switching frequency. The frequency is fixed internally at 1.2MHz. The Clock generated is used to produce ramp waveforms needed for PWM operation, and to synchronize all the internal circuits. The error amplifier is designed to monitor output voltage. The amplifier compares the reference voltage with the feedback voltage divided by the internal resistors (RFB1 and RFB2). When the FB pin is lower than the reference voltage, output voltage of the error amplifier increases. The gain and frequency characteristics of the error amplifier are optimized internally. < Maximum Current Limit> The current limiter circuit monitors the maximum current flowing through the N-channel driver transistor connected to the Lx pin, and features a combination of the current limit and latch function. When the driver current is greater than a specific level (equivalent to peak coil current), the maximum current limit function starts to operate and the pulses from the Lx pin turn off the N-channel driver transistor at any given time. When the driver transistor is turned off, the limiter circuit is then released from the maximum current limit detection state. At the next pulse, the driver transistor is turned on. However, the transistor is immediately turned off in the case of an over current state.  When the over current state is eliminated, the IC resumes its normal operation. The XC9128B type waits for the over current state to end by repeating the steps  through . If an over current state continues for several ms and the above three steps are repeatedly performed, the IC performs the function of latching the OFF state of the N-channel driver transistor, and goes into operation suspension mode. After being put into suspension mode, the IC can resume operation by turning itself off once and then re-starting via the EN pin, or by restoring power to the V IN pin. The XC9128D/XC9129D type does not have this latch function, so operation steps  through  repeat until the over current state ends. Integral latch time may be released from a over current detection state because of the noise. Depending on the state of a substrate, it may result in the case where the latch time may become longer or the operation may not be latched. Please locate an input capacitor as close as possible.

Then, measure the voltage difference between both ends of Rpull. ON Resistance is calculated by using the following formula: RLXN=0.05 ÷ ((V1 – 0.05) ÷ 0.5) where V1 is a voltage between SBD and Rpull. LX pin voltage and V1 are measured by an oscilloscope. *1: The XC9129 series does not have the AEN/ pin and the FO pin.
