TD8203
General Description
Features
The TD8203 is a current-mode and fixed frequency boost
converter with an integrated N-FET to drive white LEDs.
The series connection allows the LED current to be
identical for uniform brightness. Its low on-resistance of
NFET and low feedback voltage reduce power loss and
achieve high efficiency. Fast switching frequency(1.5MHz
typical) allows using small-size inductor and both of input
and output capacitors. An over voltage protection
function,which monitors the output voltage via OVP pin,
stops switching of the IC if the OVP voltage exceeds the
over voltage threshold. An internal soft-start circuit
eliminates the inrush current during start-up.
The TD8203 also integrates under-voltage lockout,
overtemperature protection, and current limit circuits to
protect the IC in abnormal conditions. The TD8203 is
available in a SOT-23-6A
