6.5 Vinmax, 4 Amps DC-DC switching regulator offers 96%+ efficiency in 4x4mm package

4 Amperes current rated DC-to-DC converter IC offering efficiency above 96% is launched by Analog Devices. The new ADP2164, a 6.5-V, 4-A output DC-to-DC switching regulator offers an input voltage supply range of 2.7 V to 6.5 V, an output range as low as 0.6 V using on-chip low on-resistance switching FETs. The ADP2164 in a compact 4-mm x 4-mm QFN 16-lead package 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.

ADP2164 DC-to-DC Regulator's other key features:

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.
Switching frequency can be programmed from 500 kHz to 1.4 MHz or synchronized to an external clock to eliminate beat frequencies between regulators.
Two ADP2164 regulators can also be synchronized 180 degrees out of phase to reduce input current ripple and the size of the input capacitance.
The regulator is based on a current-mode, fixed-frequency PWM (pulse-width modulation) architecture to provides high stability and transient response, and is pin-compatible with the ADP2118 5-V 3-A synchronous regulator.
Designed for high efficiency multi-rail applications, the ADP2164 operates over the -40 °C to +125 °C junction temperature range.
