Introduction:
The LTC1436AIGN-PLL#PBF is a state-of-the-art phase-lock loop (PLL) that combines both a digital PLL and a digital power supply control technology in a single package. This allows the user to have both digital and analog control over the supply voltage and frequency of their device. It is an integrated PLL that can be used for a wide range of power supply applications. The LTC1436AIGN-PLL#PBF is suitable for both single- and dual-voltage operation and provides tight control of both the AC and DC output voltages, along with critical features such as a wide fixed-frequency range, temperature-compensated frequency jitter, and full-scale current control. This device is part of the PMIC - Voltage Regulators - DC - DC Switching Controllers family.

Application Field:
The LTC1436AIGN-PLL#PBF is suitable for applications that require high frequency switching and require tight control of both the AC and the DC output voltages. This PLL can be used in power supplies, DC-DC converters, LED backlighting, and other high-power applications. It is also suitable for powering other digital devices such as logic circuits and microcontrollers.

Working Principle:
The LTC1436AIGN-PLL#PBF works by converting a low frequency clock signal into a high frequency one. The PLL has two main components – a phase detector and a voltage-controlled oscillator (VCO). The phase detector compares the frequency and phase of the low frequency clock signal to that of the VCO and adjusts the voltage of the VCO such that they remain in lock. The VCO then generates a high-frequency clock signal which can be used to power other digital devices.The LTC1436AIGN-PLL#PBF also features a temperature-compensated frequency jitter which helps to ensure that the power supplied by the device is not affected by fluctuations in temperature. The device also features full-scale current control, allowing the user to tailor the power output to their specific application.
Conclusion:
The LTC1436AIGN-PLL#PBF is a highly integrated PLL which can be used for a wide range of power supply applications. It combines both digital and analog control over the supply voltage and frequency, and also features temperature-compensated frequency jitter and full-scale current control. This makes the LTC1436AIGN-PLL#PBF an ideal choice for powering digital devices, DC-DC converters, LED backlighting, and other high-power applications.
