Product Overview

The ADP5053ACPZ-R7 is a high performance Buck Regulator enables direct connection to high input voltages up to 15.0V with no preregulators. Channel 1 and 2 integrate high-side power MOSFET 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 2 in a parallel configuration can provide a single output with up to 8A of current. Channel 3 and 4 integrate both high-side and low-side MOSFETs to deliver an output current of 1.2A. The switching frequency of the ADP5053 can be programmed or synchronized to an external clock. The ADP5053 contains a precision enable pin on each channel for easy power-up sequencing or adjustable UVLO threshold. The ADP5053 contains supervisory circuits that monitor voltage level. The watchdog timer can generate a reset if the WDI is not toggled within a preset timeout period.
  • ±1.5% output accuracy over full temperature range
  • 250kHz to 1.4MHz adjustable switching frequency
  • Adjustable/fixed output options via factory fuse
  • Single 8A output (Channel 1 and 2 operated in parallel)
  • Precision enable with 0.8 V accurate threshold
  • Active output discharge switch
  • FPWM or automatic PWM/PSM selection
  • Frequency synchronization input or output
  • Optional latch-off protection on OVP/OCP failure
