Description
General part information
STEVAL-ISA144V1 Series
The STEVAL-ISA144V1 product evaluation board provides the design engineer with a fully functional step-down switching regulator with an output current of up to 1.5 A. The L5983 integrates STMicroelectronics’ step-down switching regulator, together with all the external components required for a typical application.
The rated voltage of the input capacitor and Schottky diode rectifier’s repetitive peak reverse voltage are both 25 V, making the board capable of covering the entire 2.9 V - 18 V input voltage range of the L5983 device.
The board features an external resistor divider (R1 and R2) designed for an output voltage of 3.3 V.
