TCS4011

2.3MHz,6V/1.0A Synchyonous Step-Down converte!

Product Description

The TCs4011is a constant frequency,currentmode PWM step-down converter. The deviceintegrates a main switch and a synchronousrectifier for high efficiency without an externaSchottky diode. lt is ideal for powering portableequipment that runs from a single cell Lithium-lon(Li+)battery. The output voltage can be regulatedas low as 0.6v. The Tcs4011can also run at 100%duty cycle for low dropout operation, extendingbattery life in portable system. This device offerstwo operation modes,PWM control and PFNMode switching control, which allows a highefficiency over the wider range of the load.
