The switching frequency is 400KHz and operates with pulse width modulation (PWM). Build-in 14V / 10A MOSFET provides a high output voltage. The control loop architecture is peak current mode control; therefore slope compensation circuit is added to the current signal to allow stable operation for duty cycles larger than 50%. Current Limit Program A resistor between OC and GND pin programs peak switch current. The resistor value should be between 150k to 51kΩ. The current limit will be set from 2A to 10A. Keep traces at this pin as short as possible. Do not put capacitance at this pin. This datasheet contains new product information.

The power MOSFET wake up when the junction temperature drops 20°C under the OTP threshold temperature. Enable Mode / Shutdown Mode Drive the EN pin to ground to shutdown the IC. Shutdown mode forces to turn off all internal circuitry, and reduces the HVDD supply current to 1uA (max). The EN pin rising threshold is 1.1V. This datasheet contains new product information.

There are three important inductor specifications, DC resistance, saturation current and core loss. Low DC resistance has better power efficiency. Capacitor Selection The output capacitor is required to maintain the DC voltage. Low ESR capacitors are preferred to reduce the output voltage ripple. Ceramic capacitor of X5R and X7R are recommended, which have low equivalent series resistance (ESR) and wider operation temperature range. Diode Selection Schottky diodes with fast recovery times and low forward voltages are recommended. Ensure the diode average and peak current rating exceed the average output current and peak inductor current. In addition, the diode’s reverse breakdown voltage must exceed the output voltage. Output Voltage Programming The output voltage is set by a resistive voltage divider from the output voltage to FB. The output voltage is: R1   VOUT  1.2V 1    R2  Layout Considerations 1. The power traces, consisting of the GND trace, the LX trace and the V IN trace should be kept short, direct and wide. 2. LX、L1 and D1 switching node, wide and short trace to reduce EMI. 3. The resistive divider R1and R2 must be connected to FB pin directly as closely as possible. 4. FB is a sensitive node. Please keep it away from switching node, LX. 5. The GND of the IC, CIN and COUT should be connected close together directly to a ground plane. 6. The ground of COUT should be connected close and together directly to IC’s GND pin.
