Features
General Description
„
„
„
„
The G2602 is a current mode DC/DC converter with
an internal 2.5A, 40V switch specifically designed to
drive LEDs. The G2602 operates as a LED driver in
buck, boost and buck-boost mode. The LED current is
externally programmable with a 120mV sense resistor.
With a 500KHz operating frequency, the external inductor and input/output capacitors can all be small.
Dimming can be either analog, PWM, or PWM converting to analog with an external capacitor.
