产品概述

描述

The STEVAL-ISA091V1 is step-down switching power supply based on STMicroelectronics’ L7980 switching regulator in a QFN package.

The L7980 features an embedded power MOSFET and is capable of delivering up to 2 A of current to the load, depending on the application conditions.

The input voltage can range from 4.5 V to 28 V, while the output voltage can be set from 0.6 V to VIN.

Requiring a minimum number of external components, the device includes an internal 250 kHz switching frequency oscillator that can be externally adjusted up to 1 MHz.
