APW7711
Active
60V/3.5A, Buck Converter with Hiccup Mode
Features
- Under Voltage Protection with Hiccup Mode
- Over Temperature Protection
General Description
The APW7711 is a wide input voltage range synchronous step-down DC-DC converter that can deliver up to 3.5A output current with a 5V to 60V input supply. The exceptional efficiency and output accuracy provided in a smaller solution size make APW7711 easier to use. The APW7711 uses a peak current mode control scheme to regulate the output voltage. Auto mode selection is provided to improve the efficiency when the device operates in light load. BIAS bypass pin allows for connecting VOUT to power the internal control circuitry under the output voltage range of 6V~24V application, thereby reducing overall system power consumption for better efficiency. Under-voltage protection with hiccup mode provides cycle-by-cycle current limit protection against shorted output and soft-start eliminates inrush current during start-up. Adjustable switching frequency, soft start, current limit, FPWM option provide flexible application. Additional features such as input under-voltage lock-out, output over-voltage protection, over-temperature protection offer completely safe and smooth operation in applied conditions.
