STEVAL-ISA045V1 2 A / 1.2 V high-efficiency synchronous buck converter evaluation board based on the ST1S09
This evaluation board, based on the ST1S09 family of synchronous step-down DC-DC converters, is optimized for powering all lowvoltage applications and, generally, replaces high current linear solutions when power dissipation may cause high heating of the application environment.
It provides up to 2 A over an input voltage range of 2.7 V to 5.5 V.
A high 1.5 MHz switching frequency allows the use of tiny surface-mount components and in addition to the resistor divider to set the output voltage value, an inductor and two capacitors are required.
A low output ripple is guaranteed by the current mode PWM topology and by the use of low ESR surface-mount ceramic capacitors.
The device is thermally protected and current limited to prevent damage due to accidental shortcircuit.
The ST1S09 family is available in the DFN6 3x3 package.
