MAX1951ESA General Description

The MAX1951ESA+ is a step-down DC-DC converter with a wide input voltage range of 4.5V to 60V and a fixed output voltage of 3.3V. It is designed to deliver up to 1A of output current and operates at a high efficiency of up to 96%. This converter features a pulse-width modulation (PWM) control scheme that allows for high efficiency and fast transient response. It also includes overcurrent and thermal protection circuits to ensure safe operation. The MAX1951ESA+ is housed in an 8-pin SOIC package and operates over a temperature range of -40°C to +85°C. It is suitable for a wide range of applications, including industrial controls, automotive systems, and power-over-Ethernet (PoE) devices.
