Analog Devices LTM4703 | Demoboard EVAL-LTM4703-AZ
16V, 12A Step-Down μModule Regulator with Low Noise Reference
Overview
| Topology | Buck Converter |
| Input voltage | 4-16 V |
| Output 1 | 1 V / 12 A |
Description
The EVAL-LTM4703-AZ evaluation board is a step-down dc-to-dc switching converter featuring the LTM®4703 μModule® (micromodule) regulator. The EVAL-LTM4703-AZ is designed to deliver 12A maximum output current from a 4V to 16V input. The LTM4703 employs Silent Switcher® architecture with internal hot loop bypass capacitors to achieve both low electromagnetic interference (EMI) and high efficiency. The LTM4703 contains a current mode regulator IC, a power inductor, and a modest amount of input and output capacitance. A single resistor (R3) sets the output voltage, providing unity gain operation over the output range, resulting in virtually constant output noise independent of output voltage.
Features
- Parallel for High-Power Applications
- External or Internal Compensation
- With Optional Input EMI Filter
Typical applications
- Telecom Equipment, Networking Equipment
- Medical Equipment
- Industrial Equipment, RF Power Supplies: PLLs, VCOs, Mixers, LNAs, PAs, Low Noise Instrumentation, High Speed/High Precision Data Converters
