Description
The APW7057 is a 300kHz constant frequency voltage mode synchronous switching controller that drives external N-channel MOSFETs.
When the input supply drops close to output, the upper MOSFET remains on, achieving 100% duty cycle.
Features
- Operates from +5V Input.
- 0.8V Internal Reference Voltage - ±1.5% Accuracy Over Line, Load and Temp.
- 0.8V to V Output Range CC.
- Full Duty Cycle Range - 0% to 100%.
- Internal Loop Compensation.
- Internal Soft Start - Typical 2ms.
- Programmable Over-Current Protection - Lossless Sensing Using MOSFET RDS (ON).
- Under-Voltage Protection.
- Drives External N-Channel MOSFETs.
- Shutdown Control.
- Small.
