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 in-

ductor and input/output capacitors can all be small.

Dimming can be either analog, PWM, or PWM con-

verting to analog with an external capacitor.

The G2602 is available in TDFN-12L 3x3 and MSOP-10

(FD) package.
