LTC3727LXEUH-1#PBF is a voltage regulator specifically designed as a DC/DC Switching Controller. It is manufactured by Linear Technology Corporation, a leader in the development of analog, mixed-signal and power integrated circuits (ICs). This voltage regulator is the perfect choice when a simple control solution is needed for a variety of applications.The LTC3727LXEUH-1#PBF was designed to be used in applications where low voltage, low current, and low noise are needed, such as measurement systems, audio systems, and handheld devices. It also provides adjustable output current limit, overvoltage, overload, and temperature protection.The LTC3727LXEUH-1#PBF employs a standard P-Channel and N-Channel MOSFETs as external power switch. It can easily regulate the output voltage from 0.6V to the input voltage up to 16V allowing the manufacturer to use a simple circuit, where performance is not a priority.This voltage regulator is designed in a tiny 4 mm × 4 mm QFN package and can operate at a temperature range of -40°C to +125°C. It also has a high frequency operation of up to 500 kHz and an adjustable operating frequency between 100 kHz and 500 kHz. At the heart of the LTC3727LXEUH-1#PBF is a voltage mode PWM controller, which utilizes a logic level feedback comparator and a charge pump. The logic level feedback comparator accepts an external reference voltage, VREF, which is then compared to the internal control voltage, VC. When the voltage at VC is below the external reference voltage, VREF, the output of the comparator goes high and the Pulse Width Modulator (PWM) is enabled. The PWM will then regulate the output voltage to the desired value.For protection, the LTC3727LXEUH-1#PBF has an adjustable overvoltage protection. This protection will shut down the output when the voltage exceeds an adjustable upper threshold. It also has an adjustable output current limit and over-current protection. The over-current protection will shut down the output when the current exceeds the set limit. In addition, the LTC3727LXEUH-1#PBF features a thermal shutdown, which will shut down the output if the temperature exceeds a set limit.In summary, the LTC3727LXEUH-1#PBF is a versatile voltage regulator specifically designed for low voltage, low current, and low noise applications. It has adjustable output current limit, overvoltage, overload and temperature protection that makes it a reliable and efficient device for a variety of applications. The LTC3727LXEUH-1#PBF comes in a convenient 4 mm × 4 mm QFN package that eliminates the need for more expensive, larger packages.
