LTC1626 - Linear Technology

LTC1626 Low Voltage High Efficiency Step-Down DC/DC Converter

The LTC ®1626 is a monolithic, low voltage, step-down current mode DC/DC converter featuring Burst ModeTM operation at low output current. The input supply voltage range of 2.5V to 6V makes the LTC1626 ideal for single cell Li-Ion and 3- or 4-cell NiCd/ NiMH applications. A built-in 0.32Ω switch (VIN = 4.5V) allows up to 0.6A of output current. The LTC1626 i.

The input supply voltage range of 2.5V to 6V makes the LTC1626 ideal for single cell Li-Ion and 3- or 4-cell NiCd/ NiMH applications. A built-in 0.32Ω switch (VIN = 4.5V) allows up to 0.6A of output current. The LTC1626 incorporates automatic power saving Burst Mode operation to reduce gate charge losses when the load current drops below the level required for continuous operation. With no load, the converter draws only 165µA. In shutdo.
