GENERAL DESCRIPTION
The current-mode control architecture facilitates easy compensation design and ensures cycle-by-cycle current limit with fast response to line and load transients. The regulator offers a selectable skip-mode functionality to reduce current consumption and achieve a higher efficiency at light output load. The low RDS(ON) integrated switches ensure high efficiency at heavy loads while minimizing critical inductance, making the layout design a much simpler task with respect to discrete solutions. The IC’s simple layout and footprint assures first-pass success in new designs. The regulator features a 1MHz, factory-trimmed fixedfrequency PWM mode operation. The high switching frequency, along with the PWM current-mode architecture allows for a compact, all ceramic capacitor design. The IC features a capacitor-programmable soft-start to reduce input inrush current. Internal control circuitry ensures safe-startup into a prebiased output. Power sequencing is controlled with the enable input and power-good output.
