该LM503​​5B半桥控制器/门驱动器包含了必要的功能来实现半桥拓扑电源转换器使用的线电压前馈电压模式控制的。

该LM503​​5B是LM503​​5A半桥式PWM控制器功能的变种。 该LM503​​5B提供更高的最大占空比和更高的启动稳压器输出比LM503​​5A或LM503​​5电流。 此外，同步整流器驱动输出的LM503​​5B被关押在关断模式下低。

而LM503​​5，LM503​​5A和LM503​​5B包括浮动高边栅极驱动器，这是工作的电源电压高达105V的能力。 Both high-side and low-side gate drivers are 2A with peak capability. An internal high-voltage start-up regulator is included, as well as programmable undervoltage lockout (UVLO) and overvoltage protection (OVP). The oscillator is programmed to frequencies up to 2MHz with a single resistor. The oscillator can also be synchronized to an external clock. 电流检测输入，一个可编程的定时器提供逐周期电流限制和调节的打嗝模式过载LM503​​5 protection.The之间的差异，LM503​​5A，LM503​​5B，在总结和LM503​​5C
