LTC3429 Evaluation Kit
Linear Technology Inc.
Description
Demonstration circuit 559 is a high efficiency synchronous boost DC/DC converter with output disconnect, inrush current limiting and soft-start functions featuring the LTC3429. The board is capable of supplying 90mA from a single AA cell input or 250mA from a 2-cell input with a 3.3V output. The input range is from 1V to 3.3V. DC559 version A uses the LTC3429; version B uses the LTC3429B. The LTC3429 shifts automatically to power saving Burst Mode operation at light loads; whereas the LTC3429B operates at a fixed frequency for all loads with minimum output voltage ripple. A switching frequency of 500KHz allows up to 95% efficiency with a tiny solution footprint. Typical applications include MP3 players, GPS receivers, digital cameras, PDAs, LCD bias supplies and wireless handsets.
