HFC0100HS-LF-Z Datasheet, PDF (1/15 Pages) MPS Industries, Inc. – QUASI RESONANT CONTROLLER

The Future of Analog IC Technology
DESCRIPTION
The HFC0100 is a peak current mode controller
with Green Mode Operation. Its high efficiency
feature over the entire line and load range
meets the stringent world-wide energy
efficiency requirements.
The HFC0100 integrated with a high voltage
current source, its valley detector ensures
minimum Drain-Source voltage switching
(Quasi-Resonant operation). When the output
power falls below a given level, the controller
enters the burst mode.
The HFC0100 features variable protections like
Thermal Shutdown (TSD), Vcc Under voltage
Lockout (UVLO), Over Load Protection (OLP),
Over Voltage Protection (OVP).
The HFC0100 is available in the 8-pin SOIC8
package.
