EUP2412 500kHz Synchronous Step-Up Converter with 600mA LDO DESCRIPTION The EUP2412 provides a high efficiency 500kHz synchronous step-up converter and a low noise, high PSRR, low dropout (LDO) fixed output linear regulator with independent enable pins. 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. The EUP2412 500kHz fixed frequency synchronous step-up converter uses smaller external components producing a compact solution for a wide range of load currents. Integrated N-Channel main switch and P-Channel synchronous rectifier greatly improve converter efficiency. Internal soft-start function reduces inrush current.
