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 power supplies of White Goods. Straight lead pitch: 2.54mm, Height over PCB: < 12mm Clearance and Creepage Isolation on PCB between high and low voltage terminals: 6.5mm (4 pins removed) Input Compensation at Overcurrent components. Built-in Avalanche Energy Guaranteed High-Voltage Power MOSFET Various Protections Overcurrent Protection (OCP)---------------------------------- Pulse-by-Pulse Overload Protection (OLP) ------------------------------------- Latch Shutdown Thermal Shutdown Protection (TSD) ------------------------- Latch Shutdown http://www.DataSheet4U.net/ The function reduces the distortion of overcurrent operation point to AC input voltage change by adding three ■ Applications Switching Power Supplies for Standby Power Supplies, Home Appliances (White Goods), Digital Consumer Equipment, OA Equipment, Industry Machines, Communication Devices, Others ■ Product Lineup Product No STR-L451 STR-L472 MOSFET VDSS MIN(V) 650 900 RDS(ON) MAX (Ω) 3.95 7.7 datasheet pdf - http://www.DataSheet4U.net/ ■ Typical Application Circuit VAC VOUT STR-L400 1 2 3 D 4 8 Vcc GND Cont.
