Adjustable Vout PWM Synchronous StepUp DC-DC Converter Demonstration Board Based On The ST8R00W
Newark:
STEVAL-ISA048V2 demonstration board is based on the ST8R00W synchronous step up DC/DC converters with current output cut off function that provide up to 1A over an input voltage range of 4V to 6V and an output voltage range of 6V to 12V. The ST8R00W is the continuous mode version, that guarantees the lowest switching ripple when the device is used at light load conditions. The high switching frequency 1.2MHz allows the use of tiny surface mount components. Along with 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 mounted ceramic capacitors.
