G2602

Global Mixed-mode Technology Inc. G2602 High Voltage Multi-Topology LED Driver Features „ 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 Fre- quency „ Easy dimming : Analog, PWM or PWM Con- verting 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 Shut- down „ 12-Lead TDFN and MSOP-10 (FD) Package 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 ...
