GM7620 Datasheet | Gamma Microelectronics

PRELIMINARY FIXED FREQUENCY STEP-UP DC/DC CONVERTER .. 1.2MHz Fixed Frequency Switching Inherently Matched LED Current Adjustable Control of LED Current Drives Five White LEDs from 2V Drives Six White LEDs from 2.7V Drives Eight White LEDs from 3V Disconnects LEDs In Shutdown Uses Tiny Ceramic Capacitors Uses Tiny 1mm-Tall Inductors Regulates Current Even When VIN > VOUT Operates with VIN as Low as 1V Up to 80% Efficiency The GM7620 is a fixed frequency step-up DC/DC converter designed to operate as a constant-current source. Because it directly regulates output current, the GM7620 is ideal for driving light emitting diodes (LEDs) whose light intensity is...
