LINEAR TECHNOLOGY LTC3215 Manual
Update: 30 September, 2023
The LTC3215 is a low noise, high current charge pump DC/DC converter designed to power high current LEDs. The part includes an accurate programmable current source capable of driving loads up to 700mA from a 2.9V to 4.4V input. Low external parts count (two flying capacitors, one programming resistor and two bypass capacitors) makes the LTC3215 ideally suited for small, battery-powered applications. Built-in soft-start circuitry prevents excessive inrush cur- rent during start-up. High switching frequency enables the use of small external capacitors. LED current is pro- grammed with an external resistor. The LED is discon- nected from VIN during shutdown. An ultralow dropout current source maintains accurate LED current at very low I
