优势和特点
- Ultra-Compact Footprint: Combines a Switching Controller, MOSFETs, Inductors, and Supported Components into a Tiny 4.25mm × 4.25mm × 1.15mm Land Grid Array (LGA) Package, Saving Significant Board Space and Simplifying Layout.
- Flexible Dual/Single Output: Delivers Dual 5A Outputs or can be Paralleled into a Single 10A Output to Power Multiple Rails or Single High-Current Loads.
- Wide Voltage Range and Precision: Supports a 2.25V to 5.5V Input and a Highly Precise, Programmable 0.5V to 3.6V Output (±1% regulation) for Sensitive Digital Logic, Field-Programmable Gate Arrays (FPGAs), and Application-Specific Integrated Circuits (ASICs).
产品详情
The EVAL-LTM4723-AZ evaluation board features the LTM4723, a high-efficiency, high-power density DC-to-DC step-down μModule® regulator that operates as either a dual 5A or a single 10A supply. The evaluation board supports an input voltage range of 2.25V to 5.5V. By default, VOUT1 (Channel 1) is configured for 1.2V at 5A Max, and VOUT2 (Channel 2) is configured for 1.8V at 5A Max. The typical switching frequency is 2MHz.
The integrated loop compensation simplifies design optimization, requiring only a few output capacitors and an optional feedforward capacitor to achieve the desired loop bandwidth and load transient performance. A user-selectable operating mode allows optimization for either light-load efficiency or low-noise operation. Pulse-skipping mode (PSM) and Burst Mode® (BM) operation provide higher efficiency at light loads, while forced continuous mode (FCM) is preferred for noise-sensitive applications.
The LTM4723 employs a constant-frequency, peak current mode control architecture with integrated internal compensation, delivering fast transient response to input voltage and load changes while maintaining loop stability and providing cycle-by-cycle current limiting.
