HF500-40 – Fixed-Frequency, Flyback Regulator with Multi-Mode Control and Over-Power Line Compensation
The HF500-40 is a fixed-frequency, current mode regulator with built-in slope compensation. It combines a 700V/1Ω MOSFET and a full-featured controller into one chip for a low power, offline, fly back, switch-mode power supply. It has Multi-mode control during different load conditions. Besides, it also have Over-power line compensation and full protection features, including brown-in and brown-out, VCC under-voltage lockout (UVLO), overload protection (OLP), short-circuit protection (SCP), input over-voltage protection(OVP), VCC over-voltage protection (OVP), and over-temperature protection (OTP). The device is available in a PDIP8-7B package. and generally is designed for application such as adapters, Home Appliances Power Supplies, Set-Top Boxes and Standby Auxiliary Power.
