The HV98100T-E/CH electronic control device is a PMIC-LED driver that is designed to control a constant current source for the illumination and operation of various LED systems. It is a high performance, high efficiency, low cost device that offers a wide range of current levels and accuracy for a variety of LED applications.

The HV98100T-E/CH is a highly integrated power management integrated circuit (PMIC) that combines an array of features in order to control the current passing through an LED system. The device features a synchronous rectified buck regulator that is powered by a voltage rail of up to 20V and provides a wide range of output current of up to 250 mA for the LEDs. It can be used to drive both single color and multi-color LED systems and can control up to 4 channels from one single chip. The device also features an integrated power factor correction (PFC) circuit and has a standby current of less than 40 μA when in idle mode.

The efficiency of the HV98100T-E/CH is quite impressive and it can reach up to 95%, depending on the load current and input voltage. This device employs an advanced current-mode control technique which allows it to achieve an accurate current sensing and control despite the large output ripple. In addition, it also provides an adaptive voltage-controlled frequency and an output short-circuit protection feature.

One of the main application fields of the HV98100T-E/CH is a wide range of LED lighting systems. It is used to create high brightness and low power consumption LED lighting systems and can be used for such applications as automotive lighting, flash lighting, portable lighting, and LED displays. The LED is regulated by a constant current source that ensures that the LED will produce a constant light output despite any changes in input voltage or current.

The output current of the HV98100T-E/CH can be adjusted with the help of a low side MOSFET, which is connected in series with the LED chain. The current is adjusted by varying the duty cycle of the MOSFET, which in turn is controlled by the voltage applied across it. This voltage can be determined by an external voltage reference, or by using a built-in voltage regulator. The device also features an adaptive peak current limit feature which allows it to automatically adjust the current limit as the load changes.

Overall, the HV98100T-E/CH is a versatile, high efficiency PMIC-LED driver that can be used for a wide range of LED lighting applications. The device has low standby current consumption and can drive up to 4 channels of LEDs with a wide range of output current levels. It also features an integrated power factor correction circuit, current-mode control technique, adaptive voltage-controlled frequency, and output short-circuit protection.
