Description

General part information

LTC3606B Series

The LTC3606B is an 800mA monolithic synchronous buck regulator using a constant frequency current mode architecture.The input supply voltage range is 2.5V to 5.5V, making it ideal for Li-Ion and USB powered applications. 100% duty cycle capability provides low dropout operation, extending the run time in battery-operated systems. Low output voltages are supported with the 0.6V feedback reference voltage. The LTC3606B can supply 800mA output current.The LTC3606B’s programmable average input current limit is ideal for USB applications and for point-of-load power supplies because the LTC3606B’s limited input current will still allow its output to deliver high peak load currents without collapsing the input supply. The operating frequency is internally set at 2.25MHz allowing the use of small surface mount inductors. Internal soft-start reduces in-rush current during start-up. The LTC3606B is available in an 8-Lead 3mm × 3mm DFN package.ApplicationsHigh Peak Load Current ApplicationsUSB Powered DevicesSupercapacitor ChargingRadio Transmitters and Other Handheld Devices
