HFC0400
Fixed Frequency Flyback Controller
with Ultra-low No Load Power Consumption
The Future of Analog IC Technology
DESCRIPTION
HFC0400 i s a fixed-frequency current-mode
controller with built-in slope compensation. It
targets medium-power, off-line, flyb ack, swit ch-
mode power supplie s. At light loads, th e
controller freezes the peak current and reduces
its switching frequency down to 25 kHz to offer
excellent light-load efficiency.
At very ligh t loads, the controller enters burst
mode to achieve very low standby power
consumption.
HFC0400 offers frequency jittering to help
dissipate energy generated by conducted noise.
HFC0400 also has an X -cap discharge function
to discharg e the X -cap when the input is
unplugged.
HFC0400 features multiple prote ctions that
include ther mal shutdown (TSD), VCC under-
voltage lockout (UVLO), overloa d protectio n
(OLP), ove r-voltage protection ( OVP), and
brown-out protection.
HFC0400 is available in an SOIC8-7A package.
FEATURES
Fixed-frequency current-mode control with
built-in slope compensation
Frequency foldback down to 25kHz at light
loads
Burst mode for low standby power
consumption
Frequency jitter to reduce EMI signature

VCC under-voltage lockout with hysteresis
(UVLO)
Brown-out protection on HV pin
Overload protection with programmable
delay
Thermal shutdown (auto-restart with
hysteresis)
Latch-off for external over-voltage protection
(OVP) and over-temperature protection
(OTP) on TIMER pin
Short-circuit protection
Programmable soft start
APPLICATIONS
AC/DC adapters for notebook computers,
tablets, and smartphones
Offline battery chargers
LCD TV s and monitors

Thermal Resistance (4) θJA θJC
SOIC8-7A ................................96 ...... 45 ... °C/W
Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a fun ction of the
maximum junction temperatu re T J (MAX), the junction-to-
ambient thermal resistance θJA, and the a mbient temperature
TA. The maximu m allow able con tinuous po wer di ssipation at
any ambient te mperature is ca lculated by P D (MAX) = (T J
(MAX)-TA)/θJA. Exceeding the maximum allowable powe r
dissipation w ill cause ex cessive die tempe rature, and t he
regulator will g o into thermal shutdown. Inte rnal thermal
shutdown circuitr y pr otects the device from permanent
damage.
3) The device is not guaranteed to function outside of its
operating conditions.
4) Measured on JESD51-7, 4-layer PCB.
