LTC3409A Datasheet 600ma Low Vin Buck Regulator

Manufacturer: Linear Technology Corporation

Overview: LTC3409A 600mA Low VIN Buck Regulator in 3mm × 3mm DFN.

General Description

The LTC®3409A is a high efficiency, monolithic synchronous buck regulator using a constant frequency, current mode architecture.

The LTC3409A improves upon the LTC3409’s light load regulation in Burst Mode operation.

The output voltage is adjusted via an external resistor divider.
