DESCRIPTION:
The SCT2160A is a monolithic, step-down switchmode converter with built-in internal 14mΩ High-Side and 9mΩ Low-Side Power MOSFETs. The device achieves 6A of continuous output current from a 2.7V to 6V input voltage range, with excellent load and line regulation. The output voltage can be regulated to aslow as 0.6V. The SCT2160A, adopting the constant-on time (COT) mode control provides fast transient response and eases loop stabilization, greatly simplifies the converter off-chip configuration. The switching clock frequency can be programmed from 1.2MHz to 4MHz
for optimization of the filter size and output voltage ripple. The SCT2160A features programmable soft-start time to avoid large inrush current and output voltage overshoot during startup. The SCT2160A has MODE pin to select Pulse Frequency Modulation (PFM) operation mode to achieve the light load power save or Forced Continuous Conduction Mode (FCCM) to achieve low light load ripple. It includes full protection features, such as cycle-bycycle current limit and hiccup over current protection, output under-voltage protection, input under-voltage lockout, and thermal shutdown. The SCT2160A requires a minimal number of external components and is available in a spacesaving QFN-9L 2mm*3mm package.
