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.
