LTM8058 是一款具 LDO 后置稳压器的 2kV AC 隔离型反激式 μModule (微型模块) DC/DC 转换器。封装中内置了开关控制器、电源开关、变压器、LDO 以及所有的支持组件。LTM8058 可在 3.1V 至 31V 的输入电压范围内运作,支持 2.5V 至 13V 的输出电压范围 (由单个电阻器来设定)。另外,还集成了一个线性后置稳压器,其输出电压可调范围为 1.2V 至 12V (由单个电阻器来设定)。仅需采用输出和输入电容器便可实现完整的设计。可以采用其他组件来控制软起动控制和偏置。
LTM8058 采用耐热性能增强型、紧凑 (9mm x 11.25mm x 4.92mm) 模压树脂球栅阵列 (BGA) 封装,适合采用标准的表面贴装设备来进行自动化装配。LTM8058 采用 SnPb 或符合 RoHS 标准的端子涂层。

DC1988A:LTM8058 Demo Board | 2kV AC Isolated Flyback µModule Converter, 4.5V ≤ VIN ≤ 30V, VOUT1 = 6V @ Up to 320mA, VOUT2 = VOUT1 LDO Post Regulator
Demonstration circuit 1988A is a 2kV AC (3kVDC) isolated flyback μModule DC/DC converter with LDO post regulator featuring the LTM8058. The demo circuit is designed for a 6V flyback output and a 5V post regulator output from a 4.5V to 30V input. The current capability of the 6V flyback output varies with input voltage from about 100mA at 4.5VIN to about 320mA at 30VIN. Figure 1 shows the typical maximum output current on VOUT1 when VOUT2 is not loaded. VOUT2 is the LDO post regulator from VOUT1. The current capability of VOUT2 is limited by either the current capability of VOUT1 minus VOUT1 loading or the 300mA current limit on the LDO post regulator itself. R1 provides the necessary minimum load current to keep the VOUT1 in regulation throughout the entire input voltage range. Please see the typical performance characteristic curves in the LTM8058 data sheet to determine the minimum load current for other input/output configurations.
