Description

This demonstration board is based on the

ST8R00W family of synchronous step-up DC-DC

converters with current output cut-off function that

provide up to 1 A over an input voltage range of 4

V to 6 V and an output voltage range of 6 V to 12

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 (1.2 MHz) 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.
