The LT8619IMSE#PBF is a monolithic synchronous buck switching regulator fabricated in an 8-pin thin shrink small outline package (TSSOP). This regulator has been specifically designed to be used in a wide range of applications, most notably in driving the input of sub-regulators for dual and triple output systems. It is a PWM (pulse width modulation) DC-DC switching regulator, with features including low noise, wide frequency range, low standby current, and both adjustable and fixed feed forward and feedback modes.

The heart of the LT8619IMSE#PBF is its synchronous buck module. It has two Bucks in one package, resulting in maximum efficiency and low total cost. The Buck modules regulate the output voltage from an input voltage as high as 36V, supplying a maximum output current of 2.5A per channel. The module also includes over-voltage and over-current protection, in addition to programmable soft-start, adjustable acceleration, deceleration, and frequency control.

This high performance DC-DC switching regulator is controlled by an integrated PWM switching controller. It is capable of operating in both fixed and adjustable mode, and allows the user to specify the switching frequency, voltage regulation level and over-voltage protection level. The high switching frequency combined with the wide range of frequency settings enable the LT8619IMSE#PBF to be used in applications needing a wide range of power supplies such as 130W and higher switching frequencies. Additionally, the PWM switching controller signals the Buck module to regulate the output voltage to an accuracy of 0.4%.

The LT8619IMSE#PBF switching regulator is an ideal choice for applications requiring cost-effective, high efficiency power supplies. The wide frequency range allows for greater design flexibility and its compact package size makes it easy to use in compact applications. Additionally, the controller supports several operating modes, including high efficiency Burst Mode and current mode PWM control, making it suitable for low power standby applications.

The LT8619IMSE#PBF has a wide variety of applications that make the most of its features, such as USB charging, notebook and laptop power supplies, communication systems and battery powered devices. Its high efficiency and adjustable voltage regulation make it ideal for power-hungry applications such as mobile TV, digital photo frames, routers and set-top boxes. Its programmable soft-start and over-voltage protection also make it suitable for gaming consoles, industrial control systems, and medical devices.

In summary, the LT8619IMSE#PBF is an ideal choice for designers looking for a cost-effective, efficient, and flexible switching regulator. Its wide range of features enable it to be used in a variety of applications and its small package size makes it a great fit for compact systems. Its low noise, wide frequency range, low standby current, and both adjustable and fixed feed forward and feedback modes makes it an invaluable tool for designing low-cost, accurate, and efficient power supplies.
