The LTC7820EUFD#TRPBF is a low cost, wide input voltage range non-synchronous switching type DC-DC controller for load voltage of up to 20V. It makes use of pulse width modulation (PWM) control to regulate the output voltage, and is designed to be used with MOSFETs to create itself a switch-mode power supply (SMPS). The controller is offered in a low profile, 14 pin TSSOP package and its operating temperature range is between -40°C to +105°C.

The LTC7820EUFD#TRPBF is primarily used in applications such as industrial equipment, white goods, set-top boxes, automotive, tablets and laptops. It is equipped with a wide 4.5V to 28V input voltage range and a 1.5A maximum current limit, making it suitable for a wide range of output currents and operating conditions.

The LTC7820EUFD#TRPBF can operate in both continuous and discontinuous current modes for load currents of up to 1.5A. In addition, it also has a fast current setting feature that lets the user quickly adjust the current limit from 0A to 2A. The controller also has shutdown, enable and monitoring pins that can be used to enable and monitor the system.

The working principle of the LTC7820EUFD#TRPBF is simple. The controller works by adjusting the duty-cycle of the PWM output signal to regulate the output voltage. It does this by sensing the output voltage and comparing it to the desired voltage setpoint. If the voltage is below the setpoint, the duty-cycle of the PWM signal is increased, while if the voltage is above the setpoint, the duty-cycle is reduced. This ensures that the output voltage is automatically regulated to the desired level.

In general, the LTC7820EUFD#TRPBF is a highly reliable and cost effective DC-DC controller that can be used in a range of applications such as industrial equipment, white goods and automotive applications. Its wide input voltage range and current limit setting features make it suitable for a wide range of applications and operating conditions.
