Working Principle

The LT8304IS8E-1#TRPBF features an advanced current-mode, fixed-frequency control architecture. This system offers excellent line and load regulation over a wide input voltage range and can be configured to operate as either a buck, boost, or buck-boost converter. The PWM section controls the switch frequency and provides soft-start. The current-mode control section is responsible for sensing the output current, providing a compensated reference voltage, and controlling the duty-cycle. The integrated overcurrent protection, undervoltage lockout, and thermal shutdown make the LT8304IS8E-1#TRPBF a robust, reliable power management solution for a variety of applications.

The LT8304IS8E-1#TRPBF features a high, <200KHz numerical controlled oscillator (NCO) that allows the switching frequency to be adjustable. This allows the user to customize the switching frequency of the regulator to best suit the application. The NCO also features a spread spectrum mode that can be used to reduce system noise, EMI, and output ripple. The adjustable current-sense threshold helps provide optimal load regulation and reduce the effects of current and voltage variations.

The integrated power MOSFETs provide an efficient, low-noise power conversion. The buck-boost topology allows the regulator to step-up or step-down the input voltage as needed. The circuit also includes an undervoltage lockout (UVLO) and overcurrent protection (OCP) to prevent erroneous operation. The overcurrent protection is adjustable and can be disabled when required.
