LT8410EDC#TRMPBF

PMIC - Voltage Regulators - DC DC Switching Regulators

Integrated circuits, or ICs, are electronic circuits integrated onto a single semiconductor substrate to form an electrical component. Products such as the LT8410EDC#TRMPBF are an example of an IC used for voltage regulation. They are DC-DC switching regulators to convert input voltages to preset voltages with the ability to regulate currents up to 1A.

Applications

Voltage regulator ICs like the LT8410EDC#TRMPBF are critical devices in many modern day electronics. As the size of portable electronics continues to shrink, voltage regulators are increasingly important due to their ability to regulate voltages in low profile, small form factors. The LT8410EDC#TRMPBF is particular is able to support USB Type-C and Quick Charge 3.0 applications. It operates from a input voltage from 2.6V to 6.5V, allowing the IC to be used in single cell Lithium Ion battery designs.

The LT8410EDC#TRMPBF is an ideal choice for a variety of low power, portable applications such as mobile phones, cameras, portable media players, power banks, and small consumer appliances. It is also suitable for automotive accessories, industrial LCD displays, white goods and computer peripherals.

Working Principle

The LT8410EDC#TRMPBF works by constantly comparing an internally generated reference voltage to the output voltage at its FB pin. This comparison results in an output regulation depending on the load current that is drawn from the output of the LT8410EDC#TRMPBF. The working principle of the LT8410EDC#TRMPBF is based on the use of pulse width modulation (PWM) control.

At the start of a switching cycle, an internally generated oscillator initiates or ‘turns on’ the control switch. The width of the pulse of current into the output of the regulator determines the amount of power used to drive the output voltage to its target value. This width is then adjusted depending on the load current until the output voltage reaches the target voltage.

The LT8410EDC#TRMPBF is able to provide up to 95% efficiency, providing a low power solution with high performance. It features a point-of-load (POL) buck regulator with low 20uA quiescent current, a fast 0.5µs transient response, adjustable output voltage and over current protection.

In summary, the LT8410EDC#TRMPBF is a low power, high performance DC-DC switching regulator suitable for a variety of portable devices. It provides up to 95% efficiency, adjustable output voltage and quick transient response with over current protection. This makes it an ideal choice for mobile phones, cameras, portable media players, power banks, small consumer appliances and a variety of automotive applications.
