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.
