1 / 18 page February 2012 Doc ID 13449 Rev 2 1/18 18 ST8R00 Micropower 1 A synchronous step-up DC-DC converter Features ■ Output voltage adjustable from 6 V to 12 V ■ Output voltage accuracy: ± 2% ■ Output current up to 1 A ■ Low ripple voltage: 5 mV (typ.) ■ Synchronous rectification ■ High 90% efficiency: VO = 9 V (typ.) ■ Few external components ■ Thermal shutdown protection ■ Very small DFN8 (4 x 4 mm) package Description The ST8R00 is a synchronous PWM step-up DC- DC converter. The device is able to provide an output voltage in the range of 6 to 12 V with an input voltage from 4 to 6 V. The high switching frequency (1.7 MHz) permits the use of tiny surface-mount components. In addition to the resistor divider to set the output voltage value, only an inductor and two capacitors are required. Moreover, a low output ripple is guaranteed by the current mode PWM topology and by the use of low ESR SMD ceramic capacitors. The device is available in a very small DFN8 (4 x 4 mm) package.
