The LTC3406AB is a high efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. Supply current with no load is 200µA,dropping to <1µA in shutdown. The 2.5V to 5.5V input voltage range makes the LTC3406AB ideally suited for single Li-Ion battery-powered applications. 100% duty cycle provides low dropout operation, extending battery run time in portable systems. PWM pulse skipping mode operation provides very low output ripple voltage for noise sensitive applications. Refer to LTC3406A for applications that require Burst Mode operation.
Switching frequency 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 LTC3406AB is availablein a low profile (1mm) ThinSOT package.
