CHL8328-19CRT is a special purpose current-mode power regulator, developed by Texas Instruments. This voltage regulator is typically used to regulate current and voltage in non-isolated applications, such as communications, computer, industrial and consumer products, and so on. It is ideal for use as an adjustable output DC/DC regulator in battery-powered systems, as well as in numerous other applications.

The CHL8328-19CRT offers four functional features, single-output voltage and current, adjustable output voltage and current, overvoltage protection, and overcurrent protection. All these features give the device a vast range of applications. The single-output voltage and current is suitable for low-noise applications, such as for regulating current for a boost converter. The adjustable output voltage and current makes it highly suitable for use in power modules, as well as for applications such as high-voltage supercapacitors.

The overvoltage protection feature helps protect delicate circuits such as LCDs or LEDs from excessive current. The overcurrent protection ensures reliable operation of the device in the event of overload or short circuit. This makes it an ideal choice for high-power and/or high-current applications.

The CHL8328-19CRT can be configured to operate with either linear or pulse-width modulation (PWM). In the linear mode, an internal op-amp is used to control the output voltage by varying the duty cycle of the switch. In PWM mode, the output voltage is regulated by altering the pulse width of the switch. In this mode, the frequency of the PWM signal is also adjustable for greater control.

The CHL8328-19CRT also has low power consumption, thereby increasing overall system efficiency. It also has a low quiescent current, which reduces heat dissipation and allows the device to be used in tight spaces. Additionally, the device is immune to electromagnetic interference (EMI). This makes it a good choice for applications where EMI is a concern.

In summary, the CHL8328-19CRT is a versatile power regulator with a wide range of applications. Its four functional features make it an ideal choice for many non-isolated applications. Additionally, its low power consumption, low quiescent current, and EMI immunity make it an ideal choice for high-power, high-current and small space applications.
