DESCRIPTION
EUP2412 input voltage range is 2.2V to 5.5V, making it ideal for applications with either a 2-cell NiMH/NiCd or a single-cell lithium-ion/polymer batteries. Integrated N-Channel main switch and P-Channel synchronous rectifier greatly improve converter efficiency. Internal soft-start function reduces inrush current. When the synchronous step-up convert is disabled, the internal conduction path from SW to OUT is fully blocked. This output disconnect feature isolates the output from the input and reduces the shutdown current less than 0.1µA. The EUP2412 LDO linear regulator has an independent input supply pin and is capable of delivering up to 600mA load current. It offers high output accuracy, extremely low dropout voltage, low quiescent current and fast start-up time. LDO is designed to work with low-ESR ceramic capacitors. Only a 2.2uF ceramic output capacitor can make the device stable over the entire load range. Optionally connecting a capacitor from BYPASS pin to GND gets high PSRR.
