STR-A6000M Series

PWM Off-Line Switching Regulator ICs

Features and Benefits

Description

▪ Current mode PWM control

The STR-A6051M, STR-A6052M, STR-A6053M, and

▪ Brown-In and Brown-Out function: auto-restart, prevents

excess input current and heat rise at low input voltage

▪ Auto Standby function: improves efficiency by Burst

mode operation in light load

▫ Normal load operation: PWM mode

▫ Light load operation: Burst mode

▪ No load power consumption < 25 mW

▪ Operating frequency, f_OSC(AVG)(typ) = 67 kHz

▪ Random Switching function: reduces EMI noise, and

simplifies EMI filters

▪ Slope Compensation function: avoids subharmonic

oscillation

STR-A6079M are power ICs for switching power supplies,

incorporating a power MOSFET and a current mode PWM

controller IC in one package.

To achieve low power consumption, these products include

a startup circuit and a standby function in the controller. The

switching modes are automatically changed according to load

conditions: in normal operation, PWM mode, and in light load

conditions, burst mode. The rich set of protection features

helps to realize low component counts, and high performance-

to-cost power supply.

▪ Leading Edge Blanking function
