Shenzhen Mingjiada Electronics Co., Ltd. [Supply] LTM4703EY (ADI) µModule Buck Regulators: 16VIN, 12A Ultralow Noise Silent Switcher 3 μModule Regulator

LTM4703EY is a complete 12A step-down Silent Switcher 3 μModule® (micromodule) regulator in a tiny 6.25mm × 6.25mm × 5.07mm ball grid array (BGA) package.The package includes the switching controller, the power MOSFETs, an inductor, and support components.

Operating over an input voltage range of 3V to 16V, the LTM4703EY supports an output range of 0.3V to 6V. A single resistor sets the output voltage, providing unity gain operation over the output range and resulting in virtually constant output noise independent of the output voltage. Only bulk input and output capacitors are needed to finish the design.

The LTM4703EY employs Silent Switcher 3 architecture with internal hot loop bypass capacitors to achieve both low electromagnetic interference (EMI) and high efficiency.

Also, the LTM4703EY has an ultralow noise architecture to obtain exceptional low-frequency (<100kHz) output noise. These low EMI and low noise features make the LTM4703EY ideal for high current and noise-sensitive applications, which benefit from the high efficiency of a synchronous switching regulator.

Typical Application Of LTM4703EY

The LTM4703EY is a standalone, nonisolated step-down switching DC/DC power supply that can deliver up to 12A. The continuous current is determined by the internal operating temperature. It provides a precisely regulated output voltage programmable through one external resistor from 0.3V to 6V. The input voltage range is 3V to 16V. Given that the LTM4703 is a step-down converter, ensure that the input voltage is high enough to support the desired output voltage and the load current.
