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
