LTC3202EMSTR Description

Short technical summary and product information.

The LTC3202EMSTR by Analog Devices, Inc. is a charge pump DC/DC converter designed for white LED applications. It features low noise and constant frequency operation, utilizing fractional conversion for increased efficiency. The device can produce a regulated voltage or current up to 125mA from an input voltage range of 2.7V to 4.5V.

 

With a low external parts count, it is suitable for small, battery-powered applications. The LTC3202EMSTR includes an internal 2-bit DAC for LED brightness control, thermal shutdown protection, and a soft-start circuit to prevent inrush current. Its high switching frequency allows for small external capacitors. A low current shutdown feature reduces quiescent current to less than 1µA.

 

The LTC3202EMSTR is available in 10-pin MSOP and 3mm x 3mm DFN packages, supporting surface mount installation. Its design makes it ideal for white LED backlighting and programmable boost current source applications.
