STR-W6735 - Quasi-Resonant Topology Primary Switching Regulators

Description

The STR-W6735 is a quasi-resonant topology IC designed for SMPS applications.

It shows lower EMI noise characteristics than conventional PWM solutions, especially at greater than 2 MHz.

Features

Quasi-resonant topology IC ⇒ Low EMI noise and soft switching.
Bottom-skip operation ⇒ Improved system efficiency over the entire output load by avoiding increase of switching frequency.
Standby burst mode operation ⇒ Lowers input power at very light output load condition.
Avalanche-guaranteed MOSFET ⇒ Improves systemlevel reliability and does not require VDSS derating.
500 V / 0.57 Ω, 160 W (120 Vac input).
