LTC3606BEDD#PBF

LTC3606B is a 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. This device’s programmable average input current limit is ideal for USB applications and for point-of-load power supplies because the device’s limited input current will still allow its output to deliver high peak load currents without collapsing the input supply. Internal soft-start reduces in-rush current during start-up. It is widely used in application such as high peak load current applications, USB powered devices, supercapacitor charging, radio transmitters and other handheld devices etc.
