G2602 Global Mixed-mode Technology Inc. High Voltage Multi-Topology LED Driver 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. High Voltage : VIN up to 36V, VOUT up to 36V 2.5A Switch Current Buck, Boost or Buck-Boost Operation Current Mode PWM with 500KHz Switching Frequency Easy dimming : Analog, PWM or PWM Converting to Analog with One External Capacitor Soft Start to Avoid Inrush Current Programmable Over Voltage Protection to Limit Output Voltage VIN Under Voltage Lockout and Thermal Shutdown 12-Lead TDFN and MSOP-10 (FD) Package The G2602 is available in TDFN-12L 3x3 and MSOP-10 (FD) package.
