Overview

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
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
- Always alive 5.1 V LDO supply for tiny load demand

Single 8 A output (Channel 1 and Channel 2 operated in parallel)
Precision enable with 0.8 V accurate threshold
Active output discharge switch
FPWM or automatic PWM/PSM mode selection
Frequency synchronization input or output
Optional latch-off protection on OVP/OCP failure
Power-good flag on selected channels
UVLO, OCP, and TSD protection
48-lead, 7 mm × 7 mm LFCSP package
−40°C to +125°C junction temperature

The ADP5052 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.

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 A, 2.5 A, or 4 A. Combining Channel 1 and Channel 2 in a parallel configuration can provide a single output with up to 8 A of current.

Channel 3 and Channel 4 integrate both high-side and low-side MOSFETs to deliver output current of 1.2 A.

The switching frequency of the ADP5052 can be programmed or synchronized to an external clock. The ADP5052 contains a precision enable pin on each channel for easy power-up sequencing or adjustable UVLO threshold.

The ADP5052 integrates a general-purpose LDO regulator with low quiescent current and low dropout voltage that provides up to 200 mA of output current.
