Keywords:MC34704? i.MX25? power management?

This application note presents an analysis of using the MC34704 power management IC (PMIC) to supply a system based on the i.MX25. The focus was done on the i.MX25 itself, considering its needs in terms of voltage, current, and the power-up sequence. The DDR and flash memory requirements were also taken into account. However, the MC34704 voltage capabilities are not limited to the scenarios presented within this document.

The MC34704 family features both a 5-channel (MC34704B) and an 8-channel (MC34704A) PMIC, housed in a 56 pin QFN package with pin-to-pin compatibility between both ICs. It is meant to address power management needs for various components and loads, with a target overall efficiency of > 89% at typical loads.
