概述
Description
Introduction to MAX764CSA: The MAX764CSA is a Maxim Integrated DC-DC converter IC in the MAX764 family. It’s a compact switch‑mode regulator intended for portable or battery‑powered designs, used to derive a regulated output from a lower input rail. The device integrates (as applicable) the switching controller and switch element; external inductors, capacitors, and a feedback network are used to set the output. The “CSA” suffix identifies a specific package/variant (and sometimes temperature grade) within the MAX764 family. Typical uses include generating bias or intermediate rails for microcontrollers, LCD bias supplies, or other compact, efficient rails in small products. To design with it, consult the datasheet for exact electrical specs (input/output ranges, current capability, efficiency), pinout, and recommended external components and app circuits. Note that multiple configurations exist in the MAX764 family (boost, buck, or other topologies), so be sure you’re using the correct variant for your target rail. If you want, I can pull up the exact datasheet details.
Equivalent
Equivalents depend on the device’s function and specs. MAX764CSA’s role (DC-DC converter, LDO, or charge pump), input/output voltages, current, and package determine cross‑refs. Please provide:
- the device type or a link to its datasheet
- Vin, Vout, Iout, package/pinout
With that, I can propose RC (cross references) from TI, Analog Devices, LTC, Onsemi that match the same ratings.

Pinout
8 pins. Function: MAX764CSA is an 8‑pin switched-capacitor charge‑pump inverter that generates a negative output from a positive input (creates a negative rail using external capacitors). Typically used to produce a negative supply (e.g., -5V from +5V) from a single supply.
