ADI ADP5052ACPZ-R7

Понижающий (Buck) синхронный (4), линейный (LDO) (1)50,85В ~ 1,6В, ПРОГ.4,5 В ~ 15 В

Overview

The ADP5052ACPZ-R7 is a 5-channel Integrated Power Solution with quad buck regulators and 200mA LDO regulator that meets demanding performance and board space requirements. The device enables direct connection to high input voltages up to 15V with no preregulators. Channel 1 and Channel 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 channel 2 in a parallel configuration can provide a single output with up to 8A of current. Channel 3 and channel 4 integrate both high-side and low-side MOSFETs to deliver output current of 1.2A. The switching frequency can be programmed or synchronized to an external clock. This contains a precision enable pin on each channel for easy power-up sequencing or adjustable UVLO threshold.
