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.
Applications
„ GPS, Portable DVD Backlight
„ Desk Light and Room Lighting
