# STPMIC25APQR (Component)
## Description
Power Management IC (PMIC) – Highly integrated power management IC for microprocessor systems, operating from a 2.8 V to 5.5 V input supply. Integrates 7 synchronous buck converters, 6 adjustable general-purpose LDOs, 1 DDR termination LDO (sink/source), 1 USB PHY LDO, and 1 DDR reference voltage (VREFDDR) LDO. Features 2 MHz switching frequency, programmable power-up/power-down sequencing, user-programmable non-volatile memory (NVM), I²C and digital I/O control interfaces, and is housed in a 56-pin WFQFN (6.5 × 6.5 mm) package. Specified for an operating temperature range of −40°C to +105°C.
