MAX1772EEI

MAX1772EEI is a high-efficiency DC-DC switching regulator IC from Maxim Integrated (now part of Analog Devices) intended for portable, battery-powered devices. It combines the regulator’s control logic with a power switching element to convert a battery or supply voltage into a stable rail with high efficiency and low quiescent current. Key features typically include soft-start, enable/shutdown, current-mode control, and protection options such as short-circuit/overcurrent and thermal shutdown. The EEI suffix indicates the specific package type and lead-free/extended-temperature variant of the device.
Typical applications: mobile devices, cameras, wearables, and other handheld electronics where space and battery life are critical. For exact electrical specs, pinout, recommended operating ranges, and application notes, consult the MAX1772 datasheet and the EEI-package product page.

Key features of the MAX1772EEI (8-pin EEI package):
- Wide input voltage range with high efficiency
- Switching regulator controller for voltage step-down (PWM current‑mode control)
- Fixed-frequency operation
- Soft-start to limit inrush
- Enable input and Power-Good output
- Overcurrent/short-circuit protection and thermal shutdown
- Undervoltage and overvoltage protection (UVLO/OVLO)
- External compensation/network for stability
- Adjustable output via resistor divider
- Small 8-pin package (EEI) for compact designs

- Pin count: 8 pins (8-pin package, e.g., SOIC-8/TSSOP-8)
- Function: High-voltage, current‑mode PWM controller for a DC‑DC switching regulator (buck/boost topology) that drives an external MOSFET/inductor to regulate output voltage.

- Manufacturer: Maxim Integrated Products (now part of Analog Devices).
- What kind of company: A semiconductor company that designs and sells analog and mixed-signal integrated circuits (traditionally fabless, outsourcing manufacturing).

MAX1772EEI comes in a 28-pin Thin Quad Flat No-Lead (TQFN) package with an exposed pad.
