LD1117S33CTR集成电路（IC）的线性+开关稳压器规格书PDF中文资料

LD1117S33CTR属于集成电路（IC）的线性+开关稳压器。由意法半导体集团制造生产的LD1117S33CTR稳压器 - 线性线性稳压器用于提供稳定的输出电压，无论负载电流、输入电压或环境因素如何变化，这些输出电压通常都要保持不变。它们的工作原理要求输入电压维持在高于所需的输出电压，而且要超出某个最小量，并且在工作时会将输入端的任何多余电压转换为热量。对于大多数应用而言，虽然这种稳压器的效率低于开关模式的稳压器，但它们通常更适合对噪声高度敏感的应用。

Description

The EVSPIN32F0251S1 board is a 3-phase complete inverter based on the STSPIN32F0251 controller, which embeds a 3-phase 250 V gate driver and a Cortex®-M0 STM32 MCU. The power stage features STD17NF25 MOSFETs, but can be populated with any IGBT or Power MOSFET in DPAK or powerFLAT 6x5 package.

The board has a single-shunt sensing topology, and both the field-oriented control FOC) and sensored or sensorless 6-step control can be implemented. This allows driving permanent magnet synchronous motors (PMSMs) and brushless DC (BLDC) motors.

The evaluation board is compatible with a wide range input voltage from 20 V to 120 V DC/AC, and includes a power supply stage with the VIPER013BLS in buck configuration to generate +15 V and +3.3 V supply voltage required by the application.

Debug and configuration of FW can be performed with standard STM32 tools through the detachable STLINK-debugger. SWD and UART TX-RX connectors are also available.
