APU3039-HF-3 - Synchronous PWM Controller

Description

The APU3039 controller IC is designed to provide a synchronous Buck regulator and is targeted for applications where cost and size are critical.

The APU3039 operates with a single input supply up to 18V, and the output voltage can be programmed as low as 0.8V for low voltage applications.

Features

  • Current Limit using Lower MOSFET Sensing Using the 6V internal regulator for charge pump circuit allows single supply operation up to 18V Programmable Switching Frequency up to 400KHz Soft-Start Function 0.8V Precision Reference Voltage Available Uncommitted Error Amplifier Available for DDR Voltage Tracking.
