製品概要
製品概要
Demonstration circuit 2172A is a high input voltage, 400mA step-down regulator featuring the LTC7138. The output of the regulator can be programmed for either 5V, 3.3V or 1.8V with on-board jumpers or is adjustable from 800mV to VIN using an optional feedback divider. The input voltage range is from 4V to 140V. The LTC7138’s Burst Mode® operation, low quiescent current and internal top FET switch provide high efficiency over a wide range of loads.
