DATASHEET
1MHz, High-Efficiency, Step-Up Converter for 2 to 8 White LEDs TD8202
General Description
Features
The TD8202A/B/C is a current-mode and fixed frequency boost
converter with an integrated N-FET to drive up to 8 white LEDs
in series.
The series connection allows the LED current to be identical for
uniform brightness. Its low on-resistance of NFET and
feedback voltage reduce power loss and achieve high
efficiency. Fast 1MHz current-mode PWM operation is
available for input and output capacitors and a small inductor
while minimizing ripple on the input supply. The OVP pin
monitors the output voltage and stops switching if exceeds the
over-voltage threshold. An internal softstart circuit eliminates
the inrush current during start-up.
The TD8202A/B/C also integrates under-voltage lockout,
over-temperature protection, and current-limit circuits. The
TD8202/A/B/C is available in a SOT-23-6 packages.
