Input voltage4.2-17 V
Output 13 A
IC revision1.0

Description

The SCT2231 is a fully integrated high efficiency synchronous step-down DCDC converter capable of delivering 3A current. The devices operate over a wide input voltage range from 4.2V to 17V and fully integrate high-side power MOSFETs and synchronous MOSFETs with very low Rdson to minimize the conduction loss.With 750 kHz switching frequency, low output voltage ripple, small external inductor and capacitor size are achieved. SCT2231 adopts adaptive constant ONtime control architecture to achieve fast load transient responses for step-down applications.The SCT2231 operates in Forced Pulse Width Modulation (FPWM) mode, which maintains small output voltage ripple during light load operation.It includes full protection features, such as over current protection, output under-voltage protection,input under-voltage lockout, and thermal shutdown.The SCT2231 requires a minimal number of external components and is available in a space-saving SOT563 and TSOT23-6 package.
