TOP264VG EcoSmart Integrated Off-Line Switcher IC eDIP-12B

Description

TOP264VG EcoSmart Integrated Off-Line Switcher IC eDIP-12B TOP264VG is a member of the TOPSwitch-JX family, an integrated off-line switcher built for compact, efficient power supplies. The datasheet presents it as a monolithic device that combines the high-voltage power stage, control circuitry, oscillator, protection blocks, and EcoSmart technology into one part for flyback-style designs. In practical use, this part is meant to simplify offline power-supply design by reducing the number of external components while keeping the circuit efficient across light load, normal load, and standby conditions. The V package version is the eDIP-12B package, and the document shows it as a low-profile option for designs that need a smaller footprint and better thermal handling. Features: EcoSmart technology for energy-efficient operation. Integrated 725 V power MOSFET. Multi-mode PWM control for efficiency over the full load range. Fully integrated soft-start. Frequency options of 132 kHz and 66 kHz. Frequency jitter to help reduce EMI. Extensive protection: SCP, OCP, OPP, OVP, UV, OTP, and auto-restart. Remote-on/off and external current limit support. Specifications: Parameter TOP264VG Value Output power @ 230 VAC ±15% (adapter): 21 W Output power @ 230 VAC ±15% (open frame): 34 W Output power @ 85–265 VAC (adapter): 12 W Output power @ 85–265 VAC (open frame): 22.5 W Breakdown voltage (BVDSS): 725 V Full-frequency switching: 132 kHz Half-frequency option: 66 kHz Maximum duty cycle: 78% Soft-start time: 17 ms Thermal shutdown temperature: 142 °C Package: eDIP-12B DRAIN peak current: 2.08 A max Pinout: Applications: Notebook or laptop adapter.
