STR5A164D

The primary function of the STR5A100D series power IC is to achieve power supply systems with few external components through Primary Side Regulation, incorporating a sense MOSFET and a current mode PWM controller IC. This allows for low standby power by automatically switching between PWM operation in normal conditions and burst-oscillation under light load conditions, resulting in low component counts and high performance-to-cost power supply.

The STR5A100D series power IC supports different operation modes, including Primary Side Regulation, Constant Voltage (CV), Constant Current (CC) Control, and Auto Standby Function. These features help achieve power supply systems with few external components and low standby power consumption. The product also automatically switches between PWM operation in normal conditions and burst-oscillation under light load conditions, enhancing performance while reducing component counts and costs.

The STR5A100D series power IC for switching power supplies provides several protection features. These include Overcurrent Protection (OCP) with Pulse-by-Pulse response, Overvoltage Protection (OVP) with Auto-Restart functionality, and Thermal Shutdown Protection (TSD) also with Auto-Restart capability. These features help ensure the safety and reliability of the power supply system .
