SC1104AISTRT

Modern power applications rely on advanced integrated level control and monitoring. Systems are no longer using a slew of discrete parts but instead relying on tightly integrated electronic solutions. SC1104AISTRT is a DC/DC switching regulator controller IC with a very low quiescent current and ult-low standby power. A small 4mmx3mm package makes this a great choice for space-constrained designs.

The typical application fields for the SC1104AISTRT include power adapters, laptop power management, automotive power solutions, portable power solutions, and any other high frequency/low power DC-DC conversion systems. It can be used with inductors and capacitors to create high efficiency boost, buck, or SEPIC converter designs.

SC1104AISTRT Working Principles

The SC1104AISTRT is an analog integrated circuit that works by controlling the current delivered to the output using a voltage regulation loop. The IC can operate in both current-mode or voltage-mode and can be used with external power MOSFETs up to 80V. The IC includes all the standard features such as over-current protection, under voltage protection, over-temperature protection, overshoot reduction, time delay protection, and protection against over-voltage.

The SC1104AISTRT features a programmable soft-start and a programmable current limit that can be adjusted to optimize efficiency. The IC also features a low-noise PWM drive with a modulation frequency from 200kHz to 600kHz, programmable transition times, and a selectable sync mode. This allows for the efficient delivery of the output voltage over a wide range of frequencies and load conditions.

The SC1104AISTRT offers a very efficient power conversion solution, with high efficiency and low power consumption. The IC is also highly versatile and can be used with a wide range of components, making it a great choice for applications that require a high level of control.
