STEVAL-ISA201V1 3 A step-down switching regulator evaluation board based on the L5987 Data brief Description The STEVAL-ISA201V1 product evaluation board provides design engineers with a fully functional step-down switching regulator with an output current of up to 3 A. The STEVAL-ISA201V1 integrates the STMicroelectronics L5987 step- down switching regulator together with all the external components required for a typical application. The rated voltage of the input capacitor and the Schottky diode rectifier repetitive peak reverse voltage are both 25 V, rendering the board capable of covering the entire 2.9 V - 18 V input voltage range of the L5987 device. The board features an external resistor divider Features (R1 and R2) designed for an output voltage of 1.8 V. The output voltage can be set to a level from 1.8 V, up to 3 A DC output current 0.6 V up to VIN. The compensation network on 2.9 V to 18 V input voltage the evaluation board allows the use of an MLCC Output voltage adjustable from 0.6 V to VIN as output filter to keep the loop stable. The 430 kHz switching frequency, programmable switching frequency on the board is set to 430 in the range 250 kHz 1 MHz kHz by means of the R5 resistor connected to pin Internal soft-start and inhibit F .
