产品概述
描述
This demonstration board is based on the ST2S06B, a dual synchronous step-down DC-DC converter optimized for powering low-voltage digital cores in ODD applications and, generally, used to replace the high current linear solution when the power dissipation may cause a high heating of the application environment.
It provides up to 0.5 A over an input voltage range of 2.5 V to 5.5 V.
A high switching frequency (1.5 MHz) allows the use of tiny surface-mount components. A resistor divider to set the output voltage value, an inductor and two capacitors are required for every channel.
In addition, a low output ripple is guaranteed by the current mode PWM topology and by the use of low ESR surface-mount ceramic capacitors.
The demoboard is thermal protected and current limited to prevent damage due to accidental shortcircuit.
