Renesas ISL8270MAIRZ-T

非隔离 PoL 模块，数字4.5V14V0.6 ~ 5V25A

Overview

The ISL8270M/71M are 25A and 33A step-down DC/DC power supply modules with integrated digital PWM controller, synchronous power switches, an inductor and passives. Only bulk input and output capacitors are needed to finish the design. The 25/33A of continuous output current can be delivered without a need of airflow or a heatsink. The thermally enhanced HDA module is capable of dissipating heat directly into the PCB. The ISL8270M/71M devices use ChargeMode� control architecture, which responds to a transient load within a single switching cycle with a compensation free design. The ISL8270M/71M come with a preprogrammed configuration for operating in a pin strap mode; output voltage, switching frequency, and device SMBus address can be programmed with external resistors. More configuration such as soft-start, fault limits, current sharing, and external voltage tracking can be easily programmed or changed via PMBus compliant serial bus interface. PMBus can be used to monitor voltages, current, temperatures and fault status. The ISL8270M/71M family is supported by Intersil's PowerNavigator� software, a graphical user interface (GUI) that can be used to configure modules to a desired solution.
