The MIC5190YML-TR is a high-performance, partially integrated PWM-to-linear controller that provides a variety of features and benefits. The device features a very low quiescent current and high current drive range, making it ideal for applications such as cellular systems, battery management systems, and microprocessor-based equipment, that are becoming increasingly popular. The MIC5190YML-TR is designed to drive a linear regulator from a PWM-controlled source. This allows for high efficiency and the ability to control the output voltage at both the converter and regulator levels.

The device is built with a proprietary low-voltage power-on reset circuit that monitors both the input and output voltages. This helps ensure the correct operation of the system in a wide range of power applications and is especially useful for systems that require protection upon power-on and power-off. The MIC5190YML-TR also features wide input voltage ranges, allowing it to be used in both dual-polarity and single-polarity applications. The device is also configured with an adjustable soft start that helps prevent damage to downstream components.

In addition to its high efficiency, the MIC5190YML-TR also offers a wide range of features and benefits. It provides a programmable high-side current limit and a programmable peak current that can be used to protect downstream components from overcurrent surges. The device also features a programmable dead-time delay that allows the user to adjust the output voltage as well as the current limit. Lastly, the device is equipped with an optional on-chip programmable compensation that provides stability for any load.

In terms of its applications, the MIC5190YML-TR is a versatile and robust voltage regulator controller. It can be used to control high current loads, such as motors and actuators, as well as low power applications, such as LED lighting.
