DescriptionThe TOP248YN is designed as one kind of enhanced EcoSmart®, integrated off-line switcher that belongs to the TOP248 family. In addition, all critical parameters (i.e. current limit, frequency, PWM gain) have tighter temperature and absolute tolerances to simplify design and optimize system cost.
This TOP248YN device has some points of 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 filtering 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.
The absolute maximum ratings of the TOP248YN can be summarized as:(1)DRAIN Peak Voltage: -0.3 V to 700 V;(2)DRAIN Peak Current: 7.20 A;(3)control voltage: -0.3 V to 9 V;(4)control current: 100 mA;(5)Lead Temperature: 260 °C;(6)Operating Junction Temperature: -40 °C to 150 °C;(7)Storage Temper-ature: -65 °C to 150 °C.
