PV88090规格书详情
General 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.
PV88090 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 provide up to 400 mA. PV88090 provides dynamic voltage control
(DVC) via I
2C command to support adaptive adjustment of the supply voltage based on the processor
loading. All power blocks have over-current circuit protection and the start-up timing can be
controlled through the I
2C interface. The supply voltages of PV88090 control can be realized via
direct register writes through the I
2C interface to the operating point of the system.
PV88090 includes over-temperature and over-current protection for increased system reliability,
without external sensing components. A soft-start mechanism limits the inrush current from the input
node and secures a slope-controlled rail activation. A standby mode provides reduced power
consumption. Optional standby operation for DDR memory, auxiliary buck, and analog core LDO are
configurable in PV88090 for optimizing the power rails. The PV88090is available in a 30-pin QFN
package and is specified from -40 °C to 85 °C ambient temperature.
