Description

MAX1772EEI is Maxim Integrated’s high-efficiency switching regulator/power-management IC. It combines integrated power MOSFETs and control logic to form a DC-DC converter (buck/boost family depending on variant) for converting a wide input voltage to a stable output rail in portable and automotive applications.
Key points:
- Wide input range, programmable output via feedback resistors
- Fixed switching frequency, enable/soft-start, current limit
- Protective features: undervoltage lockout, overcurrent protection, thermal shutdown
- Typically requires external inductor and input/output capacitors; uses synchronous or conventional rectification depending on variant
- Package suffix EEI denotes a specific ordering package/footprint
Common applications:
- CPU/FPGA/ASIC power rails, battery-powered devices, automotive electronics, LED driver contexts
Note:
- For exact specifications (input range, Vout, max current, switching frequency) and the exact package/pinout, consult the MAX1772EEI datasheet and product page.

Features

Here are the main features of the MAX1772EEI (offline switcher controller):
- 700V integrated high-voltage MOSFET for offline flyback operation (no external FET required)
- Primary-side regulation with current-mode PWM and peak-current limit
- High-efficiency operation using valley switching/quasi-resonant techniques
- Programmable switching frequency with EMI-friendly jitter
- Soft-start to suppress inrush and startup overshoot
- Robust protection: cycle-by-cycle overcurrent/short-circuit protection, overvoltage protection, and thermal shutdown
- Safe startup with UVLO (undervoltage-lockout) and enable input
- Fault reporting/monitoring options (status/output flags)
- Suitable for compact offline power supplies; optimized for small footprint and low standby power
Note: exact pinout and optional PSR/opto configurations may vary by package variant.

Package

8-pin SOIC (Small-Outline Integrated Circuit) package.

Pinout

Pin count: 16 pins (EEI package variant). Function: High-voltage PWM controller for DC-DC switching regulators (switching-regulator controller with integrated driver).

Manufacturer

Maxim Integrated (now part of Analog Devices) is the manufacturer of the MAX1772EEI. Maxim is a semiconductor company that designs and manufactures analog, mixed-signal, and power-management integrated circuits for consumer, automotive, and industrial applications.

Application

Applications: high-efficiency DC-DC conversion and power management for battery-powered and portable devices, notebooks/ultra-portables, automotive power-management, telecom/network equipment, and industrial/consumer electronics requiring robust voltage regulation.

Equivalent

I can help, but I need specifics. Do you want pin‑compatible cross-references or functionally similar parts? MAX1772EEI is a high‑voltage buck/boost controller, and exact equivalents depend on Vin/Vout/Iout, package, and features. Please provide required Vin range, Vout, Iout, package, and any must‑have features (synchronous, UVLO, soft-start). I can fetch precise cross-references.
