MAX629ESA

MAX629ESA is a Maxim Integrated power-management IC in the MAX629 family. It’s a DC-DC switching-regulator controller that provides the regulation logic (reference, error amplifier, oscillator) used to drive an external power stage (inductor, diode, and switch transistor) to generate a stable lower output from a higher input.
The ESA suffix identifies the package/lead finish (an 8‑pin, RoHS‑compliant variant) and the device’s temperature rating for that family. Typical features include adjustable output via feedback resistors, current- or voltage‑mode control, soft-start, overcurrent/short-circuit protection, and thermal shutdown.
Common applications are compact, point‑of‑load power supplies for telecom, computing, and portable equipment. For exact electrical specs, pinout, and application details, refer to the current MAX629ESA datasheet and related Maxim application notes.

I don’t have the exact pin count and function for MAX629ESA without the specific datasheet/package. The “ESA” suffix denotes a particular Maxim package variant (often 16-pin), but the pinout depends on the package. Please provide the package (e.g., SO-16/SSOP-16) or a datasheet link, and I’ll give you the exact pin count and function.
