PMIC - Voltage Regulators - DC DC Switching Regulators

The LT3473AEDE#PBF application is a type of DC-DC switching regulator. It is designed to be used as a step-up voltage converter, allowing for efficient, power-saving conversions from low voltage sources to output voltages. This application can be used for a variety of applications requiring a stable, variable output voltage, including lighting, industrial and consumer applications.

Features

• Wide Input Voltage Range, 1.8V to 18V
• High Output Voltage up to 60V
• Fast Transient Response
• Extremely Low Quiescent Current
• Optional Output Disconnect
• Selectable Overkill Protection
• Thermally Enhanced 20-Lead Package

Working Principle

The LT3473AEDE#PBF application is based on a switching-mode step-up power converter topology. It uses a single inductor and a switch to store energy and convert a low input voltage to a high output voltage. As a PWM switching regulator, it is designed to be easily integrated into small form factor applications and offer improved efficiency, lower current requirements, and increased reliability for low power devices.

The LT3473AEDE#PBF utilizes an internal N-channel MOSFET as the power switch. When the switch is ON, current is drawn from the input supply and stored in an inductor. When the switch is OFF, the stored energy is released and used to power the output voltage. By controlling the amount of time that the switch is ON and OFF, the output voltage can be modulated with a high degree of accuracy.

The LT3473AEDE#PBF also includes the overkill protection for enhanced output voltage accuracy and stability. The LT3473AEDE#PBF overkill protection feature monitors the current level of the output voltage and shuts down the power switch if the current exceeds the overkill limit. This helps to prevent excessive voltage spikes or current flows.
