ADP5050 - 5-Channel Integrated Power Solution

Description

The ADP5050 combines four high performance buck regulators and one 200 mA low dropout (LDO) regulator in a 48-lead LFCSP package that meets demanding performance and board space requirements.

The device enables direct connection to high input voltages up to 15 V with no preregulators.

Features

  • Wide input voltage range: 4.5 V to 15 V ±1.5% output accuracy over full temperature range 250 kHz to 1.4 MHz adjustable switching frequency Adjustable/fixed output options via factory fuse or I2C interface I2C interface with interrupt on fault conditions Power regulation Channel 1 and Channel 2: programmable 1.2 A/2.5 A/4 A sync buck regulators with low-side FET driver Channel 3 and Channel 4: 1.2 A sync buck regulators Channel 5: 200 mA low dropout (LDO) regulator Single 8 A output (Channel 1 a.
