描述 Description

TLVM236x5 是一款 1.5A 或 2.5A、36V 输入同步直流/直流降压电源模块，它在紧凑且易于使用的 3.5mm × 4.5mm × 2mm、11 引脚 QFN 封装中整合了引线框上倒装芯片 (FCOL) 封装、功率 MOSFET、集成电感器和启动电容器。小型 HotRod™ QFN 封装技术可提高热性能，确保可在高环境温度下工作。器件可通过电阻反馈分压器配置为 1V 至 6V 输出。

TLVM236x5 旨在满足常开型工业应用的低待机功耗要求。自动模式可在轻负载运行时进行频率折返，在输入电压 (V IN) 为 13.5V 时实现 1.5µA 的空载电流消耗和高轻负载效率。PWM 和 PFM 模式之间的无缝转换以及低 MOSFET 导通电阻可确保在整个负载范围内提供出色的效率。

TLVM236x5 采用具有内部补偿的峰值电流模式架构，用于维持稳定运行和超小的输入电容。RT 引脚可用于在 200kHz 至 2.2MHz 范围内设置频率，来避开噪声敏感频带。
