APU3146 - DUAL SYNCHRONOUS PWM CONTROLLER

Description

The APU3146 IC combines a Dual synchronous Buck controller, providing a cost-effective, high performance and flexible solution.

The APU3146 can configured as 2independent or as 2-phase controller.

The 2-phase configuration is ideal for high current applications.

Features

  • Dual Synchronous Controller with 180 out-of-phase Configurable to 2-Independent Outputs or 2-Phase Single Output Current Sharing Using Inductor's DCR Current Limit using MOSFET's RDS(ON) Hiccup/Latched Current Limit Latched Over-Voltage Protection Vcc from 4.5V to 16V Input Programmable Switching Frequency up to 500KHz Two Independent Soft-Starts/ Shutdowns 0.8V Precision Reference Voltage Available Power Good Output External Frequency Synchronization.
