General Description
The RT9269 is a compact, high efficient LED driver
with high flexibility of application configurations in
charge pump mode or in boost rectifier mode,
delivering Tens of mA constant output current for
driving 1~4 white LED’s.
The 0.25V low reference voltage minimized the
power loss across the current-setting resistor.
The wide applicable VDD range makes RT9269
suitable for 1 to 4 battery cell applications as well as
being supplied with 2.5/3.3/5/6V system powers.
The 500kHz high switching rate minimized the size
of external components. Besides, the 17
μ
A low
quiescent current together with high efficiency
maintains long battery lifetime.
The output current is set with 1 external resistor.
And the chip enable (CE) pin can be used for tuning
the LED brightness by controlling the ON/OFF duty
with external clock. RT9269 is provided in SOT-26
package.
