Beschreibung

The HF01B00/01/02/03/04 is a flyback regulator with Green Mode Operation. Its high efficiency feature over the entire input/load range meetsthe stringent world-wide energy-saving requirements.

The HF01B00/01/02/03/04 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 up

The HF01B00/01/02/03/04 provides various protections, such as Thermal Shutdown (TSD), VCC Under Voltage Lockout (UVLO), Over LoadProtection (OLP), Over Voltage Protection (OVP) and so on.

The HF01B00/01/02/03 is available in PDIP8-7B package. And HF01B04 is available in PDIP8-7B and SOIC8-7B packages.
