【应用】拓尔微同步升降压控制器助力66W快充车载充电器，支持34V输入电压，输出电压可通过编程配置

时间： 2023-02-11 来源：世强

技术问答

随着智能设备的更新迭代，日常使用的电子设备种类越来越多，高性能的用电设备消耗电量的速度也越来越快。对于日常上班和外出旅游的用户，在汽车上给设备充电的车载充电器不可或缺，常规功率的车载充电器也逐渐满足不了用户的需求。因此，市面上出现了很多快充车载充电器，如华为、摩米士等推出了66W、100W等不同功率的车充。

拓尔微TMI5700推出的同步升降压DCDC控制器可根据高于、低于或等于输出电压的输入电压进行操作。宽3.9V至28V输入，输出电压可通过FB引脚编程或通过I2C接口配置，基于电流模式控制，从3.08V至21.5V，每步10mV，并由PWM占空比控制。

它还具有可调软启动功能，并提供保护功能，包括输入UVLO和OVP、逐周期电流限制、输入平均电流限制、输出平均电流保护、输出过载保护（OLP）、OVP和热关机。此外，它还具有可选的强制连续传导模式（FCCM）或不连续传导模式，适用于轻负载。

下图为TMI5700典型电路连接图，供设计参考：

图2. TMI5700典型电路图

以下为TMI5700的参数特点：

1、宽输入电压范围从3.9V到28V。

2、可编程VOUT范围从0.59V到30V。

3、可调频率：100kHz~1MHz。

4、集成了I2C兼容接口，用于输出电压设置、平均电流设置、电缆补偿。

5、输入欠压锁定、打嗝模式下的输出短路保护、FB输出过电压保护。

综上所述，TMI5700很适合于车载充电器上的应用场景。

【应用】集成电感的降压DCDC芯片IM6001助力车载DCDC设计，5V转3.3V效率高达93%

车载DCDC产品辅助电源中主控芯片供电一般采用5V转3.3V，之前不少设计会采用线性稳压器或低压DCDC设计，但以上两种方案分别存在效率低和布板面积过大问题，本文推荐拓尔微集成电感同步降压芯片IM6001。

【应用】国产升压DCDC STI3508在数据采集器中的应用，开关频率1MHz

在数据采集器中，使用单节锂电池供电，输出大约3.6V，需要升压到12V给传感器供电，拓尔微电子的输入电压范围2.5V至7V、输出电压高达28V的升压DCDC STI3508就可应用在此，实现将3.6V升压到12V。
