Product Summary
The APW7080KAI-TRG is a 4A, asynchronous, step down converter with integrated 80mΩ 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 APW7080KAI-TRG 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 APW7080KAI-TRG 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 5uA.
