Product Summary

The TOP250YN is a TOPSwitch-GX family extended power, design flexible, ecosmart, integrated off-line switcher. The TOP250YN uses the same proven topology as TOPSwitch, cost effectively integrating the high voltage power MOSFET, PWM control, fault protection and other control circuitry onto a single CMOS chip. Many new functions of the TOP250YN are integrated to reduce system cost and improve design flexibility, performance and energy efficiency.

Parametrics

TOP250YN absolute maximum ratings: (1)CONTROL Current: 100 mA; (2)LINE SENSE Pin Voltage: -0.3 V to 9 V; (3)CURRENT LIMIT Pin Voltage: -0.3 V to 4.5 V; (4)MULTI-FUNCTION Pin Voltage: - 0.3 V to 9 V; (5)FREQUENCY Pin Voltage: -0.3 V to 9 V; (6)Storage Temperature: -65 ℃ to 150 ℃; (7)Operating Junction Temperature: -40 ℃ to 150 ℃; (8)Lead Temperature: 260 ℃.

Features

TOP250YN features: (1)Extended power range for higher power applications; (2)No heatsink required up to 34 W using P package; (3)Features eliminate or reduce cost of external components; (4)Fully integrated soft-start for minimum stress/overshoot; (5)Externally programmable accurate current limit; (6)Wider duty cycle for more power, smaller input capacitor; (7)Separate line sense and current limit pins on Y/R/F packages; (8)Line under-voltage (UV) detection: no turn off glitches; (9)Line overvoltage (OV) shutdown extends line surge limit.
