Analog Devices Inc. introduced the ADP2370/71 15-V, 800-mA output DC-to-DC regulator optimized for better energy efficieny in battery-powered applications using multiple alkaline/NiMH, lithium cells, or other standard power sources.
The ADP2370/71 regulators offer a wide input voltage supply range of 3.2 V to 15 V and require only three external components to reduce overall footprint. The ADP2370/71 offer greater than 93 percent conversion efficiency, enabling designers to support a higher load in a smaller area. During light load conditions, the ADP2370/71 can be configured to automatically switch to a low-quiescent power-save mode for additional battery life savings. The ADP2371, otherwise identical to the ADP2370, also offers a quick output discharge feature to ensure that the output bypass capacitors are completely discharged so that the processor can wake up in a known state.
Wide input voltage range up of 3.2 V to 15 V
Output voltage is adjustable from 0.8 V to input voltage (capable of 100 percent duty cycle operation). Fixed output voltage options are also available: 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.0 V, 3.3 V and 5 V.
Ultra low Iq <14 ľA in Power Saving Mode (PSM)
Requires only three external components to reduce overall solution size
Peak efficiency up to 93 percent improves system power efficiency and reduces thermal dissipation
Synchronization input to minimize input ripple current and reduce input filter design
Precision-enable input and power-good feature enable a simple and reliable start-up sequence
Internal compensation and soft start simplifies design
Quick output discharge (ADP2371) automatically discharges the output when the device is disabled
