General Description
The APW7080 is a 4A, asynchronous, step-down converter with integrated 80mW P-channel MOSFET. The device, with current-mode control scheme, can convert 4.5~26V input voltage to the output voltage adjustable from 0.8 to 90% VIN to provide excellent output voltage regulation.
The APW7080 regulates the output voltage in automatic PSM/PWM mode operation, depending on the output current, for high efficiency operation over light to full load current.The APW7080 is also equipped with power-onreset, soft-start, and whole protections (undervoltage, over temperature, and current-limit) into a single package. In shutdown mode, the supply current drops below 5mA.
This device, available in an 8-pin SOP-8P package, provides a very compact system solution with minimal external components and good thermal conductance.
