FEATURES
● Adjustable Output Voltage from +0.75V to +5.5V - 0.75V Reference Voltage - ±1% Accuracy Over-Temperature GENERAL DESCRIPTION
In Pulse Frequency Mode (PFM), the APW8815 provides very high efficiency over light to heavy loads with loadingmodulated switching frequencies. In PWM Mode, the converter works nearly at constant frequency for low-noise requirements. The APW8815 is equipped with accurate positive currentlimit, output under-voltage, and output over-voltage protections, perfect for NB applications. The Power-OnReset function monitors the voltage on VCC and PVCC to prevent wrong operation during power-on. The APW8815 has a 1.2ms digital soft-start and built-in an integrated output discharge device for soft-stop. An internal integrated soft-start ramps up the output voltage with programmable slew rate to reduce the start-up current. A soft-stop function actively discharges the output capacitors. The APW8815 is available in 14pin TSSOP, 14pin QFN and 16pin TQFN packages respectively.
