概述

Description

ADP1853ACPZ-R7 is Analog Devices’ high‑efficiency, synchronous buck regulator. It integrates the high‑side MOSFET and control circuitry in a compact ACPZ package (RoHS, tape‑and‑reel, -R7). It steps down a higher DC input to a lower, stable output for point‑of‑load rails in mobile and embedded electronics.
Key features include current‑mode PWM control for fast transient response, wide input range, adjustable output via an external feedback network, enable/shutdown, soft‑start to limit inrush, overcurrent/short‑circuit protection, and thermal shutdown. It delivers high efficiency across loads with good line/load regulation and low quiescent current, ideal for battery‑powered devices and compact systems.
Applications: CPU/GPU/memory or FPGA core rails, RF transceivers, and other digital logic power rails.
For precise electrical specs, package details, and layout guidance, consult the ADP1853 data sheet and product page on Analog Devices’ website.

Features

Here are the main features of ADP1853ACPZ-R7 (typical for the ADP1853 family; verify exact numbers in the datasheet):
- High-efficiency synchronous buck regulator
- Wide input voltage range (suitable for automotive/industrial environments)
- Output voltage adjustable via external feedback network (fixed options available)
- Up to multiple-ampere continuous output current
- Internal soft-start for controlled startup
- Enable/Shutdown control for sequencing
- Overcurrent/short-circuit protection
- Thermal shutdown protection
- Undervoltage lockout (UVLO) with hysteresis
- Light-load/power-saving mode options for improved efficiency
- Fixed or programmable switching frequency (as applicable to device variant)
- Small 8-pin LFCSP package (ACPZ) with RoHS-compliant lead-free options
Note: Specifics (exact input range, output range, and currents) should be confirmed from the official datasheet for ADP1853ACPZ-R7.

Package

Package type: 8‑lead LFCSP (Lead Frame Chip-Scale Package). R7 indicates Tape & Reel packaging.

Pinout

Pin count: 8 pins in the ACPZ package.
Function: ADP1853ACPZ-R7 is a high-efficiency 3-A step-down (buck) switching regulator with an integrated high-side MOSFET. Key functions include VIN input, GND reference, EN/UVLO (enable), FB (feedback for output regulation), SW (switching node to the inductor), BST (bootstrap for gate drive), and PGOOD (power-good output).

Manufacturer

The ADP1853ACPZ-R7 is manufactured by Analog Devices, Inc. (ADI).
Analog Devices is an American multinational semiconductor company that designs, manufactures, and markets analog, mixed-signal, and digital signal processing integrated circuits, including power management devices. It is headquartered in Norwood, Massachusetts.

Application

ADP1853ACPZ-R7 is a high-efficiency synchronous buck regulator for on‑board power management. Typical applications include:
- Portable consumer electronics (smartphones, tablets, wearables, cameras) needing compact PMIC/POUR rails
- Embedded systems and DSP/ASIC/FPGA power rails
- Networking/communications equipment (routers, modems, set‑top boxes)
- Automotive and industrial battery-powered systems requiring reliable, small, efficient DC‑DC conversion

Equivalent

There isn’t a published exact cross-reference for ADP1853ACPZ-R7. To identify equivalents, use Analog Devices’ Cross-Reference tool or contact ADI for substitutes. In general, look for a 3-A buck regulator with Vin ≈ 2.5–5.5 V, Vout either adjustable or in the 1–5 V range, similar switching frequency, and the same package pinout. For a drop-in within the same family, consider other ADP18xx devices (e.g., ADP1850/ADP1851) with matching ratings.
