Analog Devices LTM4703 12A Silent Switcher 3 μModule

The Analog Devices LTM4703 is a high-efficiency, ultra-low noise DC-DC step-down regulator that integrates a switching controller, MOSFETs, inductor, and key components into a compact 6.25mm × 6.25mm × 5.07mm BGA package. With a wide 3V to 16V input range and an adjustable 0.3V to 6V output, it simplifies power design while delivering up to 12A continuous output current.

Engineered with Silent Switcher 3 architecture, the LTM4703 minimizes EMI emissions using internal hot loop bypass capacitors, ensuring low noise and high efficiency. Its 8μVRMS ultra-low RMS noise (10Hz-100kHz) makes it ideal for noise-sensitive applications, including telecom, networking, RF power supplies, instrumentation, and medical electronics.
