Introduction

The LT3692AHUH#PBF is a family of DC/DC buck switching regulators. It is a synchronous monolithic buck regulator that features an integrated 1.5A or 2A switch, accurate current limit and is truly programmable with an external resistor. It is designed to generate a low-noise, low-ripple output voltage with a minimum of external components. The LT3692AHUH#PBF is a high-performance, highly efficient, switch-mode buck regulator designed for various applications.

Application Field

The LT3692AHUH#PBF can be used in a variety of applications. It is most commonly used in portable and handheld equipment, including cell phones and portable medical devices. It can also be used for automotive, consumer, and industrial applications. It can be used for a variety of applications such as battery management, power conversion, timing, DC/DC power supplies, and power over Ethernet (PoE).

Working Principle

The LT3692AHUH#PBF features a synchronous monolithic buck regulator. It uses a voltage-mode control method with an internal oscillator to control the pulse width modulation (PWM) for consistently tight regulation even under light-load conditions. An external current-sensing resistor sets the over-current limit. The device also has built-in circuit protection features such as over-temperature, under-voltage, and over-voltage protection. The LT3692AHUH#PBF supports either a single-ended or differential current-mode control input to optimize transient response and light-load efficiency.

It also features a programmable soft-start, which can be adjusted to meet a variety of requirements, such as over-current protection and minimum on time. In addition, the device has adjustable valley current limit, adjustable frequency ramp rate and adjustable slope compensation. The LT3692AHUH#PBF also features a total-shutdown current of less than 0.5μA, which reduces its power dissipation.

Conclusion

The LT3692AHUH#PBF from Linear Technology is a high-performance, high-efficiency synchronous monolithic buck regulator that is designed for a variety of applications including portable and handheld equipment, automotive, consumer, and industrial applications. The device features a synchronous monolithic buck regulator, voltage-mode control, and an internal oscillator, amongst other features. It also features built-in circuit protection features, adjustable frequency ramp rates, and adjustable soft-start. Overall, the LT3692AHUH#PBF is a powerful regulator for its size and provides consistent, reliable performance for a variety of applications.
