Working Principle

The LTC2926CGN#PBF is an integrated power management IC (PMIC) that provides synchronous buck, boost, or buck-boost voltage regulation, low dropout (LDO) linear regulator, overvoltage and overcurrent protection, and temperature monitoring. The device includes an onboard precision analog-to-digital converter (ADC) capable of providing digital information on battery state and temperature.

The LTC2926CGN#PBF integrates a buck converter, a boost regulator, and a low-dropout (LDO) linear regulator. For the buck converter, a pulse width modulation (PWM) signal is used to control the voltage output. The boost regulator is configured to provide a regulated output voltage when the input voltage is less than the output voltage. The LDO regulator is used to provide a low-noise, low-power supply for digital and analog circuits, and also allows for dynamic voltage scaling.

Overvoltage and overcurrent protection are provided by the LTC2926CGN#PBF to protect against unexpected disruptions in power supply. The device also includes a temperature sense circuit in order to allow the system to shut down if the temperature of the system exceeds the maximum operating temperature.

The wide input voltage range (6V-20V) makes the LTC2926CGN#PBF well suited for a variety of applications, such as battery management, automotive, consumer, and embedded systems. The device also includes a number of enhanced features such as skip mode, power-down/sleep/auto-shutdown modes, and dynamic voltage scaling.
