ADI ADP5050ACPZ-R7

降压同步（4），线性（LDO）（1）50.85V ~ 1.6V，PROG4.5V ~ 15V

Overview

The ADP5050ACPZ-R7 is a high performance Buck Regulator enables direct connection to high input voltages up to 15V with no preregulators. Channel 1 and 2 integrate high-side power MOSFETs and low-side MOSFET drivers. External NFETs can be used in low-side power devices to achieve an efficiency optimized solution and deliver a programmable output current of 1.2, 2.5 or 4A. Combining Channel 1 and 2 in a parallel configuration can provide a single output with up to 8A of current. Channel 3 and 4 integrate both high-side and low-side MOSFETs to deliver output current of 1.2A. The switching frequency of the ADP5050ACPZ-R7 can be programmed or synchronized to an external clock. The ADP5050ACPZ-R7 contains a precision enable pin on each channel for easy power-up sequencing or adjustable UVLO threshold. The ADP5050ACPZ-R7 integrates a general-purpose LDO regulator with low quiescent current and low dropout voltage that provides up to 200mA of output current.
