PMIC - Voltage Regulators - DC DC Switching Regulators have been widely used in all areas of the industry. The LT1376HVIS is a high-performance synchronous step-down switching regulator, which is suitable for low to medium current, wide input voltage range applications. It offers excellent efficiency and accuracy, high-performance and flexible switching back-end solutions.

The LT1376HVIS is a high-performance, low-side synchronous rectified PWM regulator with an internal high side MOSFET. It is capable of supplying up to 500mA output current over an input voltage range of 3 to 40V and can operate in pulse-skip mode or forced continuous conduction mode. The LT1376HVIS is designed to provide up to 90% efficiency in wide load and input voltage range. It also features low output-voltage ripple, fast transient response and an internal Pulse-By-Pulse current limit.

The LT1376HVIS features a wide range of features and protection features. It has a fast over voltage response time and an adjustable soft start time to keep the output voltage within the specified voltage tolerance range. It also has over-current protection, thermal shutoff and short-circuit protection. The LT1376HVIS also provides external under-voltage lock-out and margin control.

The LT1376HVIS can be used in a large number of applications, from low power consumer electronics to high power industrial applications. It’s small size and low quiescent current makes it ideal for applications where space and power dissipation are at a premium. It has been successfully tested in a variety of automotive, medical and industrial applications.

The working principle of the LT1376HVIS is based on the operation of a standard synchronous rectified buck switching regulator. The LT1376HVIS uses two MOSFETs in parallel to form a full-bridge circuit. In steady state, the output MOSFET turns on and off in order to regulate the output voltage. The other MOSFET, called the freewheel MOSFET, is responsible for storing energy for the next on-time period. The freewheel MOSFET is turned off when the output MOSFET is on, and the output MOSFET is turned off when the freewheel MOSFET is on. This prevents the output voltage from being clamped by the reverse current from the freewheel MOSFET.

In addition to the standard operating features, the LT1376HVIS also offers a wide range of additional features. It provides an adjustable switching frequency, programmable soft-start time and an adjustable output voltage margin. It also has over-current and thermal protection and a glitch-freeenable signal to reduce noise and EMI. The LT1376HVIS also includes an active voltage positioning (AVP) feature that can be used to reduce the output voltage undershoot and overshoot.

The LT1376HVIS is an excellent choice for a variety of switching regulators applications. Its wide range of features, high efficiency and small size make it an ideal choice for automotive, medical and other industrial applications. Its low quiescent current makes it an ideal choice for low power applications. Its wide input voltage range and fast transient response make it suitable for a range of high power industrial applications.
