DESCRIPTION
FEATURES
The EVHFC0500-S-00A Evaluation Board is
designed to demonstrate the capabilities of
HFC0500. HFC0500 is a fixed-frequency
current mode controller with built-in slope
compensation. At light load condition, it freezes
the peak current and reduces its switching
frequency down to 25kHz. As a result, it offers
excellent efficiency at light load. At very light
load, the controller enters burst mode. So very
low standby power consumption can be
achieved.
•
The EVHFC0500-S-00A is designed for TV,
monitor and it typically drives 39W with dual
outputs. One is 16VTYP, 1.5A load and the other
is 5VTYP, 3A load from 90V AC /60Hz to
265V AC /50Hz.
The
EVHFC0500-S-00A
has
excellent
efficiency and meets 2kV IEC61000-4-5 surge
immunity and EN55022 conducted EMI
requirements. HFC0500 features variable
protections like Thermal Shutdown (TSD), Vcc
under Voltage Lockout (UVLO), Over Load
Protection (OLP), Over Voltage Protection
(OVP), Over Temperature Protection (OTP) and
Brown-Out Protection.
HFC0500 is available in the SOIC8-7A package.
