Overview

The RY3420 is a high-efficiency monolithic synchronous buck regulator using a constant frequency, current mode architecture. The device is available in an adjustable version. Supply current with no load is 40μA and drops to <1uA in shutdown. The 2.5V to 5.5V input voltage range makes the RY3420 ideally suited for single Li-Ion battery powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable systems. PWM/PFM mode operation provides very low output ripple voltage for noise sensitive applications. Switching frequency is internally set at 1.2MHz, allowing the use of small surface mount inductors and capacitors. Low output voltages are easily supported with the 0.6V feedback reference voltage. The RY3420 is offered in a low profile (1mm) 5-pin, thin SOT package, and is available in an adjustable version.
