Overview
STR-L400 Series Power IC for Quasi-Resonant Type Switching Power Supply with High Efficiency, Low Noise Low-Height, and Enough Creepage Isolation (>6mm) between High and Low Voltage Terminals ■ General Descriptions The STR-L400 series products are power ICs for quasi-resonant switching type power supplies, incorporating a power MOSFET and a controller IC in the SIP-10 package.
The product achieves high efficiency and low noise power supply systems by the quasi-resonant operation.
The product is recommended for the systems requiring low-height and enough clearance and creepage isolation between high and low voltage terminals.
SIP-10 ■ Features Quasi-Resonant Operation Current-Mode Control Built-in Oscillator for Low Frequency Operation The operation with low frequency of 50µs OFF time (around 22 kHz), until the quasi-resonant signal becomes valid, reduces the stress on components at startup and load-shorted.
SIP-10 Package (Sanken designation: STA-10L), recommended for auxiliary powe...
