The Future of Analog IC Technology
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 150kHz,
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 Load
Protection (OLP), Over Voltage Protection
(OVP) and so on.
The HF01B00/01/02/03 is available in PDIP8-7
package. And HF01B04 is available in PDIP8-7
and SOIC7.

Description
Valley switching detector of the auxiliary flyback signal. It ensures Discontinuous Conduction
Mode (DCM) operation with valley switching over the entire input/load range. This pin also
offers OVP detection.
Supply voltage pin. Typically connect a 22μF bulk capacitor and a 0.1uF ceramic capacitor
to this Pin. When VCC is charged to 12V, the internal high voltage current source turns off
and the IC starts switching; when it falls back to 8V, the high voltage current source turns on
again and the IC stops switching.
Not connected. This pin ensures adequate creepage distance.
Drain of the internal MOSFET. Input for the start up high voltage current source.
Source of the internal MOSFET. Input of the primary current sense signal.
Source of the internal MOSFET. Input of the primary current sense signal.
The IC Ground.
This pin sets the primary peak current limit, by directly connecting an optocoupler to this pin
to close the feedback loop. A feedback voltage of 3.7V on this pin will trigger an Over Load
Protection while 0.5V will trigger a Burst Mode operation. The regulator leaves Burst Mode
Operation and enters normal operation when the FB voltage reaches 0.7V
