STR3W400MXD Overview
The STR3W400MXD series is power IC for switching power supplies, incorporating a power MOSFET and a current mode PWM controller IC. The operating mode of the IC automatically changes to green-mode or burst oscillation mode according to load in order to improve the all load efficiency. The product achieves high cost-performance power supply systems with few external ponents.
