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. This regulator offers skip-mode functionality to reduce current consumption and achieve a higher efficiency at light loads. 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 high switching frequency (1MHz), along with the PWM current-mode architecture allows for a compact, all-ceramic capacitor design. The IC features a capacitor-programmable slew-rate control to reduce input current at the startup and when the output changes state under VID control. Internal control circuitry ensures safe-startup into a prebiased output. Power sequencing is controlled with the enable input and power-good output. The IC is available in a 20-bump (4 x 5 array), 2.5mm x 2mm, WLP package and is fully specified over the -40NC to +85NC temperature range.
