TOP256EG [Power Integrations]

Multi-mode operation maximizes efficiency at all loads. Features include new eSIP-7F and eSIP-7C packages with low thermal impedance (2 °C/W) and low height for space-limited adapters. Simple mounting using a clip. Extended creepage distance from DRAIN pin. No heatsink required up to 35 W (universal input) and 48 W (230 VAC). Output overvoltage protection (OVP) is user programmable. Line undervoltage (UV) detection prevents turn-off glitches. Line overvoltage (OV) shutdown extends surge limit. Accurate programmable current limit. Optimized line feed-forward for ripple rejection. 132 kHz frequency reduces transformer size. Half frequency option for video applications. Frequency jittering reduces EMI filter cost. Improved auto-restart delivers <3% of maximum power in fault conditions. Hysteretic thermal shutdown with automatic recovery. Fully integrated soft-start for minimum start-up stress.
