MPS HF01B01DP-LF

隔离8V ~ 20V45 W

Overview

The HF01B01DP-LF-Z is a flyback regulator with Green Mode Operation. Its high efficiency feature over the entire input/load range meets the stringent world-wide energy-saving requirements.The HF01B01DP-LF-Z is an integrated current mode controller with a 700V FET. Its valley switching detector ensures minimum Drain-Source voltage switching every cycle, per Quasi-resonant operation. When the output power falls below a given level, the regulator enters the burst mode to lower the stand-by power consumption.An internal minimum off time limiter prevents the switching frequency from exceeding 150 kHz, which is below the CISPR-22 EMI start limit. Internal 2.4ms soft start prevents the excessive inrush current during start upThe HF01B01DP-LF-Z provides various protections, such as Thermal Shutdown (TSD), VCC Under Voltage Lockout (UVLO), Over Load Protection (OLP), Over Voltage Protection (OVP) and so on.The HF01B01DP-LF-Z is available in PDIP8-7B package.
