General Description
The G2602 is a current mode DC/DC converter with an internal 1.5A, 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 120m V sense resistor. With a 1MHz 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.
The G2602 is available in a TDFN-12L 3x3 package.
Applications
- GPS, Portable DVD Backlight
- Desk Light and Room Lighting
- Industrial Display Backlight
