Visão Geral

Description

ADP1853ACPZ-R7 is Analog Devices’ compact, high‑efficiency synchronous buck DC‑DC converter. It integrates both high‑side and low‑side MOSFET switches and is designed to regulate a low-voltage input down to a user‑set output rail with high efficiency for battery-powered and small‑form‑factor electronics. It typically uses fixed-frequency, current‑mode control with an external feedback network to set Vout, and includes protections such as undervoltage lockout, overcurrent/short‑circuit protection, and thermal shutdown. The device supports a wide input range suitable for portable supplies and can deliver a few amps of output current, making it suitable for CPUs, memory, and peripheral rails. The ACPZ suffix refers to the specific package (lead‑free/low‑profile) and -R7 indicates tape‑and‑reel shipping. In short, it’s a ready‑to‑use, efficient buck regulator for compact power designs.

Features

ADP1853ACPZ-R7 features (concise):
- 1 A step-down DC-DC converter with integrated high-side switch
- Input voltage range: 2.3 V to 5.5 V
- Output: adjustable via external feedback network (typical 1.0 V–3.3 V range; fixed options available per variant)
- Switching frequency: ~600 kHz (typ)
- High efficiency with good load regulation
- Low quiescent current and fast transient response
- Enable (shutdown) input
- Soft-start to limit inrush
- Protective features: current limit / short-circuit protection, thermal shutdown, undervoltage lockout
- Packaging: 8-pin LFCSP (ACPZ), -R7 denotes tape-and-reel
- Operating temperature: wide range (-40 °C to +125 °C)
- RoHS-compliant and suitable for portable/mobile applications
Note: for exact electrical values (range limits, pinouts, and recommended external components), consult the latest Analog Devices datasheet.

Pinout

- Pin count: 8 pins (MSOP-8 package, ACPZ).
- Function: ADP1853ACPZ-R7 is a synchronous step-down (buck) regulator with integrated high-/low-side FETs. Pin functions (typical):
