产品详情

LTM^®4620A 是一款完整的双通道 13A 或单通道 26A 输出开关模式 DC/DC 电源，与 LTM4620 相比，其 V_OUT 带宽更宽而且效率更高。封装中内置了开关控制器、功率 FET、电感器和所有的支持组件。LTM4620A 可在一个 4.5V 至 16V 的输入电压范围内运作，支持两个输出电压范围均为 0.6V 至 5.3V (由单个外部电阻器来设定) 的输出。该器件的高效率设计能够为每个输出提供高达 13A 的连续电流。仅需少量的输入和输出电容器。

这款器件支持频率同步、多相操作、突发模式 (Burst Mode^®) 操作以及用于电源轨排序的输出电压跟踪功能，并具有一个负责监视器件温度的内置温度二极管。高开关频率和一种电流模式架构的运用实现了针对电压和负载变化的快速瞬态响应，而并未牺牲稳定性。

故障保护功能包括过压和过流保护。该电源模块采用专有的节省空间和耐热性能增强型 15mm x 15mm x 4.41mm LGA 封装和 15mm x 15mm x 5.01mm BGA 封装。LTM4620A 具有符合 SnPb (BGA) 或 RoHS 标准的引脚涂层。

DC2268A-B

查看此评估套件详细信息

Demonstration circuit 2268A-B is a high efficiency, high density, dual 18A, switch mode step-down power supply on a compact 1.5' × 1.2' PCB. It features the LTM4620A μModule regulator. The input voltage is from 5.5V to 16V. The output voltage is programmable from 0.6V to 5V. DC2268A-B can deliver up to 13A maximum in each channel. As explained in the data sheet, output current derating is necessary for certain V_IN, V_OUT, and thermal conditions. The board operates in continuous conduction mode in heavy load conditions. For high efficiency at low load currents, the resistor jumper (R1/R2) selects pulses-kipping mode for noise sensitive applications or Burst Mode^® in less noise sensitive applications. Two outputs can be connected in parallel for a single 26A output solution with optional jumper resistors.

Demonstration circuit 1759A features the LTM4620AEV, the high efficiency, high density, dual 13A, switch mode step-down power module regulator. The input voltage is from 5.5V to 16V. The output voltage is programmable from 0.6V to 5V. DC1759A can deliver 13A maximum current from each channel. As explained in the data sheet, output current derating is necessary for certain V_IN, V_OUT, and thermal conditions. The board operates in continuous conduction mode in heavy load conditions. For high efficiency at low load currents, the MODE jumper (JP1) selects pulse-skipping mode for noise sensitive applications or Burst Mode^® operation in less noise sensitive applications. Two outputs can be connected in parallel for a single 26A output solution with optional jumper resistors. The board allows the user to program how its output ramps up and down through the TRACK/SS pin. The output can be set up to either coincidentally or ratiometrically track with another supply’s output. Remote output voltage sensing is available for improved output voltage regulation at
the load point.
