HF01B00/01/02/03/04
Off Line High Voltage
Quasi Resonant Regulator
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
FEATURES
Internal Integrated 700V MOSFET
High Level of Integration, Requires Very
Few External Components
Universal Input Voltage (85~265VAC)
Quasi-Resonant Operation over the Entire
Input and Load Range
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.
Maximum Switching Frequency Limited
Valley Switching for High Efficiency and
Better EMI Performance
Active Burst Mode for Low Standby Power
Consumption
Internal High-Voltage Current Source for
Start-Up
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

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