Description

The TS3406 is a high efficiency monolithic synchronous buck regulator using a 1.5MHz constant frequency, current mode architecture. The device is available in an adjustable version. Supply current with no load is 300A and drops to <1A in shutdown. The 2.5V to 5.5V input voltage range makes the TS3406 ideally suited for single Li-Ion batterypowered applications. 100% duty cycle provides low dropout operation, Switching frequency of TS3406 is internally set at 1.5MHz, allowing the use of small surface mount inductors and capacitors. The internal synchronous switch increases efficiency and eliminates the need for an external Schottky diode. Low output voltages are easily supported with the 0.6V feedback reference voltage. The TS3406 can supply 600mA of load current at VCC=3V.
