STEVAL-ISA146V1
4 A step-down switching evaluation board based on the ST1S50
Data brief
Description
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 V_IN.
