Analog Devices’ highly integrated synchronous regulator reduces board space and enables highly efficient power management

NORWOOD, USA: Analog Devices Inc. (ADI) has introduced the ADP2164, a 6.5-V, 4-A output DC-to-DC regulator featuring a high conversion efficiency of greater than 96 percent. The highly integrated ADP2164 regulator offers an input voltage supply range of 2.7 V to 6.5 V, an output range as low as 0.6 V and includes low on-resistance switching FETs to maximize efficiency while reducing board space.

The ADP2164 provides very high efficiency in a compact 4-mm x 4-mm QFN 16-lead package. This new DC-to-DC regulator is designed for multi-rail, point-of-load applications ranging from communication infrastructure to industrial devices that demand small size, fast transient performance and highly accurate voltage regulation. Unlike other 5-V regulators, the maximum input range of the ADP2164 is 6.5 V, which provides additional safety headroom.

Key features
* Maximum input voltage range up to 6.5 V provides additional headroom over a 5.5-V sources.
* Peak efficiency up to 96 percent improves system power efficiency and reduces thermal dissipation.
* Synchronization input and selectable phase-shift feature to minimize input ripple current and reduce input filter design complexity.
* Precision-enable input, voltage tracking input and power-good feature enables a simple and reliable start-up sequence.
* Internal compensation and soft start simplifies design.
