Product Summary

The TOP249YN is a TOPSwitch-GX used 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 are integrated to reduce system cost and improve design fiexibility, performance and energy efficiency.

Parametrics

TOP249YN absolute maximum ratings: (1)DRAIN Voltage: -0.3 V to 700 V; (2)DRAIN Peak Current: 8.64A; (3)CONTROL Voltage: -0.3 V to 9 V; (4)CONTROL Current: 100 mA; (5)LINE SENSE Pin Voltage: -0.3 V to 9 V; (6) CURRENT LIMIT Pin Voltage: -0.3 V to 4.5 V; (7)MULTI-FUNCTION Pin Voltage: - 0.3 V to 9 V; (8)FREQUENCY Pin Voltage: -0.3 V to 9 V; (9)Storage Temperature: -65 to 150℃; (10)Operating Junction Temperature: -40 to 150℃; (11)Lead Temperature: 260℃.

Features

TOP249YN 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; (10)Line feed-forward with maximum duty cycle (DCMAX) reduction rejects line ripple and limits DCMAX at high line; (11)Frequency jittering reduces EMI and EMI ?ltering costs; (12)Regulates to zero load without dummy loading; (13)132 kHz frequency reduces transformer/power supply size; (14)Half frequency option in Y/R/F packages for video applications; (15)Hysteretic thermal shutdown for automatic fault recovery; (16)Large thermal hysteresis prevents PC board overheating.
