SP3406 600mA Buck Converter DESCRIPTION SP3406 is a high efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. The device is available in an adjustable version and fixed output voltages, such as 1.5V,1.8V,etc. Supply current with no load is 30uA and drops to <1uA in shutdown. The 2.5 to 6.5V input voltage range makes the SP3406 ideally suitable for single Li-Ion, two to four AA battery-powered applications. In low dropout operation mode, the duty cycle can reach to 100%, extending battery life in portable systems. PWM pulse skipping mode operation provides very low output ripple voltage for noise sensitive applications. Switching frequency is internally set at 1.5MHz, allowing the use of small surface mount inductors and capacitors.
