Special purpose voltage regulators are used in various industries and applications, ranging from consumer electronics to military and aerospace applications, to provide reliable and accurate power. The CHL8214-00CRT is a special purpose voltage regulator designed to efficiently convert an input voltage of up to 36 V into an output voltage with tight regulation and wide current range. It is suitable for applications with high power density and high efficiency requirements.

The CHL8214-00CRT employs a proprietary dual-level regulation control architecture which provides high output accuracy at low power levels. Its switching topology ensures low electrical noise, offer excellent load and line regulation and a wide input voltage range. It also utilizes a combination of high technology components and innovative circuit design to provide reliable and efficient voltage conversion.

The CHL8214-00CRT features a wide input voltage range of 2.7 V to 36 V and a wide output voltage range of 0.75 V to 34 V. Its output voltage can be adjusted by a separate voltage reference or with a separate feedback divider. Furthermore, the regulator is capable of delivering up to 3 A at low external component count. Additionally, it is designed to be short-circuit proof and overload proof.

The working principle of the CHL8214-00CRT is based on its dual-level control architecture. First, the voltage reference input drives a low-power comparator to detect the output voltage. Then, based on the feedback voltage, the error amplifier will adjust the soft-start control block output to achieve the desired output voltage level. A power MOSFET is used to regulate the output. The power MOSFET\'s conduction and switching are regulated by a Pulse Frequency Modulated (PFM) controller, which ensures that the output voltage remains constant under varying loads and input voltages.

The CHL8214-00CRT is suitable for many applications including DC-DC converters, battery-powered electronics, power line conditioning, power amplifiers, and other high-power density and high-efficiency applications. It is also an ideal choice for applications that require a wide output voltage range and high power efficiency. By employing advanced technology, the CHL8214-00CRT offers better performance in terms of output voltage accuracy, power efficiency, and ripple rejection than other voltage regulators on the market today.
