February 19, 2012 – Analog Devices ( www.analog.com , NASDAQ: ADI), a global leader in high-performance semiconductors for signal processing and a global data converter market leader, today introduced the ADP2370/71 15V, 800mA output DC-DC regulator, which can improve energy efficiency in battery-powered applications using multiple alkaline/NiMH, lithium batteries, or other standard power sources.

The highly integrated ADP2370/71 regulator features an input voltage supply range of 3.2V to 15V and requires only three external components, allowing for a reduction in overall footprint. With an outstanding conversion efficiency of over 93%, the ADP2370/71 enables designers to support higher loads in a smaller footprint. In particular, it can be configured to automatically switch to a low standby mode under light load conditions, further extending battery life. The ADP2371 supports a rapid output discharge function, which accelerates processor wake-up times by completely discharging the bypass capacitor at the output stage. Aside from this feature, the ADP2371 is identical to the ADP2370 in all specifications.

The ADP2370/71 uses Analog Devices' proprietary high-speed current mode constant frequency PWM control technique, which provides excellent stability and transient response characteristics, thereby minimizing output voltage ripple. The switching frequency of these regulators can be synchronized to an external clock to reduce the beat frequency between regulators. The ADP2370/71 operates in a junction temperature range of −40°C to +125°C and is supplied in a miniaturized package of 3mm × 3mm QFN-8 leads.
