STR6S161HXD - Sanken

STR6S161HXD Off-line PWM Controllers

The STR6S161HXD is power IC for switching power supplies, incorporating a power MOSFET and a current mode PWM controller IC. The operation mode is automatically changed, in response to load, to the fixed switching frequency, to the switching frequency control, and to the burst oscillation mode. Thus, the power efficiency is improved. The product achieves hig.

Features

● Pb-free (RoHS compliant)
● Improving circuit efficiency (Since the step drive control can keep VRM of secondary rectification diodes low, the circuit efficiency can be improved by low VF)
● Current Mode Type PWM Control
● AC Input Voltage Detection Function - Overvoltage Protection Function (HVP) - Brown-In and Brown-Out Function
● No Load Power Consumption, PIN < 40 mW
● Automatically changed operation mode in response to load conditions - Fixed switching frequency mode, 100 kHz (typ.) in normal operation. - Green mode, 25 kHz (typ.) to 100 kHz (typ.) in middle to light load. - Burst oscill.
