The EL7531IYZ-T7 from Renesas is a Synchronous, Integrated Step-down PMIC that is ideal for PDA and pocket PCs, bar code readers, cellular phones, portable test equipment, Li-Ion battery-powered devices, and other small form factor (SFP) applications. It requires an input voltage of 2.5 - 5.5 V. This PMIC includes an internally-compensated voltage mode controller and automatic PFM/PWM mode control to adjust the frequency up to 12 MHz. It benefits from over-current and over-temperature protection circuits to prevent over-load or thermal breakdown-related damages. This RoHS-compliant PMIC is available in a surface-mount package that measures 3.0 x 3.0 x 1.1 mm.
