Información del producto
Resumen del producto
HF500A-30 is a fixed-frequency, EMI optimized current mode regulator with built-in slope compensation, multi-mode control and overpower line compensation. Device combines a 700V MOSFET and a full-featured controller into one chip for a low power, offline, flyback, switch-mode power supply with EMI optimization. At medium and heavy loads, the regulator operates at a fixed frequency with frequency jittering. Jittering helps reduce EMI energy on switching frequency and its harmonics. Under light-load conditions, the regulator holds the peak current and reduces its switching frequency to 25KHz to offer excellent efficiency. At very light loads, the regulator enters burst mode to achieve low standby power consumption. It also features overpower line compensation to ensure that overload protection point is independent of input voltage. HF500A-30 is available in a PDIP8-7B package. Applications includes power supplies for home appliances, set-top boxes, standby and auxiliary power adapters.
