Description

The ST8R00 family of low quiescent current,synchronous PWM step-up DC-DC converters offer high efficiency even in light load conditions. The ST8R00 accepts a positive input voltage from 4 to 6V and provides an output voltage in the 6 to 12V range.

The ST8R00 is developed in two versions: Burst mode and Continuous mode. The Burst mode version functions in discontinuous mode, allowing the device to maintain the regulated voltage in no load conditions by turning off the internal switches. The Continuous mode version,ST8R00W, guarantees the lowest switching ripple when the device is used at light load conditions.

The high switching frequency and internally limited peak inductor current permit the use of small, low-cost inductors. Only three external components are required: an inductor and two ceramic capacitors.

The ST8R00 is suitable for use in equipment where low noise, low ripple and low supply current are required. The ST8R00 is available in a very small DFN8 4x4mm package.
