DESCRIPTION
HFC0300 is a variable off-time controller that
uses
a
fixed-peak–current
technique
to
decrease its frequency as the load lightens. As
a result, it offers excellent efficiency at light-load
while optimizing the efficiency under other load
conditions.
When the frequency decreases to threshold,
the peak current decreases with the decreasing
load to prevent mechanical resonance in the
transformer. The controller enters burst mode
when the output power falls below a given level.
The HFC0300 features various protections such
as thermal shutdown, VCC under-voltage lockout,
overload protection, short-circuit protection, and
over-voltage protection.
The HFC0300 is available in SOIC-7 package.
FEATURES
 Variable Off-Time, Current Mode Control
 Universal Main Supply Operation (85VAC to
265VAC)
 Frequency Foldback as Load Lightens
 Peak-Current Compression to Reduce
Transformer Noise
 Active-Burst Mode for Low Standby Power
Consumption
 Internal High-Voltage Current Source
 Internal 200ns Leading Edge Blanking
 Thermal Shutdown (Auto Restart with
Hysteresis)
 VCC Under-Voltage Lockout with Hysteresis
 Over-Voltage Protection on VCC Pin
 Timer-Based Overload Protection
 Short-Circuit Protection
 Natural Spectrum Shaping for Improved
EMI Performance
APPLICATIONS
Battery Charger for Portable Electronics
Standby Power Supply
Switched-Mode Power Supplies
