GENERAL DESCRIPTION
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.

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
  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

APPLICATIONS
  Small cell base stations
  FPGA and processor applications
  Security and surveillance
  Medical applications
