STEVAL-ISA146V1:4 A step-down switching evaluation board based on the ST1S50

The STEVAL-ISA146V1 is a product evaluation board used to evaluate the ST1S50, a 500 kHz fixed-frequency PWM synchronous step-down regulator. The ST1S50 operates from a 4.0 V to 18 V input, while it regulates an output voltage as low as 0.8 V and up to 0.88 x VIN.
