概述

Description

MAX764CSA is a Maxim Integrated (now Analog Devices) boost switching regulator from the MAX764 family. It’s designed to take a low-voltage source (like a battery) and generate a higher, regulated output rail for biasing or driving circuits in portable electronics. The CSA suffix indicates a specific package/temperature variant; check the datasheet for exact pinout and electrical specs.
Key points:
- Type: boost (step-up) DC-DC converter
- Features: high efficiency, enable/shutdown, current limit, thermal shutdown, low quiescent current
- External components: requires appropriate inductor and support passives per datasheet
- Applications: LCD bias rails, camera flash pre-charge circuits, backlight drivers, portable instrumentation
For precise specifications (input range, output voltage, switching frequency, efficiency) and package details, refer to the MAX764CSA datasheet.

Package

8-pin SO-8 (surface-mount Small-Outline) package.

Pinout

Pin count: 8 pins.
Function: Inverting charge-pump DC-DC converter (voltage inverter) that generates a negative output rail from a positive input, using external capacitors.

Manufacturer

Manufacturer: Maxim Integrated (Maxim Integrated Products, Inc.) — the MAX764CSA is a Maxim part. Maxim was acquired by Analog Devices in 2021.
What kind of company: Maxim is a semiconductor company that designs and manufactures analog and mixed‑signal integrated circuits (power‑management ICs, voltage regulators, data converters, amplifiers, interface devices) for industrial, automotive, communications and consumer markets.

Application

MAX764CSA is a high‑efficiency DC‑DC switching regulator (buck) used to generate low-voltage rails from higher inputs. Applications include:
- Battery-powered portable devices and handhelds
- Microprocessor/FPGA core and I/O supplies
- Telecom and networking equipment DC‑DC conversion
- Consumer electronics (set‑top boxes, DVD players, etc.)
- Automotive and industrial power‑management systems
- Instrumentation and sensors requiring compact, low‑noise rails
