MAX1723EZK+T

MAX1723EZK+T is Maxim Integrated’s (now ADI) high-efficiency DC-DC switching regulator intended for portable power management. The “EZK” designation refers to the 8-pin EZ-pack package, and “+T” indicates tape-and-reel packaging for automated assembly.
Key points:
- It’s a switching regulator with integrated control circuitry and power switch for generating a stable output from a low-voltage source (e.g., a battery or USB).
- Features typically include adjustable output, enable/shutdown, soft-start, current limit, and thermal/shutdown protection for robust operation.
- Benefits: high efficiency, low quiescent current, suitable for battery-powered handheld devices, LED backlights, and other portable power-applications.
- Applications: portable electronics power rails, backlight driver stages, and other DC-DC conversion needs.
Note: exact electrical specs (input range, output voltage range, switching frequency, efficiency, protection behavior) vary by variant. For precise data, consult the MAX1723EZK+T datasheet and package sheet. If you want, I can summarize pinout and typical application circuits.

Here are the typical features of the MAX1723 family (as represented by the MAX1723EZK+T Eval Kit). For exact numbers, please consult the datasheet and the EZK+T user guide.
- High-efficiency buck-boost DC-DC regulator suitable for battery-powered apps
- Wide input range to cover various battery chemistries and configurations
- Fixed-frequency, current-mode control for stable regulation and fast transients
- Output voltage is adjustable via feedback network (external resistors)
- Enable/shutdown control and soft-start to limit inrush and power-on behavior
- Protection features: overcurrent/short-circuit, overvoltage, and thermal shutdown
- Low quiescent current suitable for sleep or standby modes
- Small footprint package with minimal external components for compact designs
- Evaluation Kit (EZK+T) includes reference designs, test points, and user documentation to speed evaluation
Note: Exact specs (input range, output range, efficiency, current capability) vary by revision. Check the official MAX1723 datasheet and EZK+T kit documentation for precise figures.

The MAX1723EZK+T is supplied in an 8-pin μMAX package (SOT‑23‑8 equivalent). The “+T” suffix denotes tape-and-reel packaging for automated assembly.

The MAX1723EZK+T is made by Maxim Integrated (now part of Analog Devices, Inc.). Maxim/Analog Devices is a semiconductor company that designs and manufactures analog and mixed‑signal integrated circuits—specializing in power-management, signal-conditioning, data-conversion, and interface ICs for industrial, automotive, communications, and consumer markets.

Application areas of MAX1723EZK+T include:
- Battery-powered portable devices (phones, handhelds, wearables)
- Portable medical equipment
- USB adapters and other line-powered supplies
- Automotive and industrial power-management systems
- Embedded telecom/industrial equipment requiring regulated rails

I don’t have live cross‑reference access. Please confirm the MAX1723’s key specs (topology: boost/step‑up, input/output voltage range, max switch current, switching frequency, and package) and I’ll suggest close drop‑in equivalents from TI, Analog Devices/Linear, Microchip, and ON Semiconductor.
