Description
MAX1723EZK+T is a Maxim Integrated (now Analog Devices) high‑efficiency synchronous buck regulator IC. It integrates the power MOSFETs and control circuitry needed to convert a higher input voltage to a lower, stable output for digital circuits, ideal for battery-powered portable devices.
Key points:
- Synchronous buck converter with reduced external components and high efficiency.
- Adjustable output via feedback (and enable, soft-start, current limit).
- Protection features: undervoltage lockout, overcurrent, overtemperature.
- Small package option (EZK); +T denotes tape-and-reel shipping.
- Applications: mobile/handheld products, PMIC sub-regulators, any compact DC‑DC step-down needs.
Note: exact input voltage range, output voltage, switching frequency, and current capability depend on the specific variant. For precise specs and typical application circuits, consult the MAX1723EZK+T datasheet.
