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 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 HFC0100 is available in the 8-pin SOIC8
package.
