PV88090 - High Efficiency 3-Channel Buck Converter

Description

PV88090 is a power management unit (PMU) optimized for supplying systems with central processing units (CPU), input/output (I/O), and dual data rate (DDR) memory.

The target application range covers television, set-up box, wifi routers, and enterprise access point and network addressable servers.

Features

  • a two-phase buck converter providing up to 9.5 A current, and two one-phase buck converters for dual date rate (DDR) memory and auxiliary power. High efficiency is achieved over a wide load range by using automatic pulse frequency modulation (PFM). All power switches are integrated, eliminating the need for external Schottky diodes are not needed. This optimizes power efficiency and reduces the external component count. Two LDO regulators with programmable output voltage are integrated and provi.
