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),
V
CC
Under Voltage Lockout (UVLO), Over Load
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.
Notes:
1. Maximum continuous power in a non-ventilated enclosed
adapter measured at 50℃ ambient temperature.
2. Maximum continuous power in an open frame design at 50℃
ambient temperature.
3. 230Vac or 110/115Vac with doubler.
4. The junction temperature can limit the maximum output power.
