DESCRIPTION

The HF01B00/01/02/03/04 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 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),

Protection

(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.
