The TPS56C231L is a single, D-CAP3™ control mode, synchronous buck converter requiring a very low external component count. The TPS56C231L is a high-efficiency, cost effective, low quiescent current synchronous buck converter with integrated FETs. A mode pin is used to select output current limit, switching frequency, and forced continuous conduction mode (FCCM) and discontinuous conduction mode (DCM) operation. The device uses D-CAP3 control mode to provide a fast transient response, good line, load regulation, no requirement for external compensation, and supports low ESR output capacitors. Additionally, the TPS56C231L provides adjustable soft start, undervoltage lockout inputs, and a power-good output. Rated input voltage and output current ranges for the evaluation module are given in Table 1-1.
The TPS56C231LEVM evaluation module (EVM) is a single, synchronous buck converter providing 1.2 V at 12 A from 4.5-V to 17-V input. This user’s guide describes the TPS56C231LEVM performance.
| EVM | Input Voltage (VIN) Range | Output Current (IOUT) Range |
|---|---|---|
| TPS56C231LEVM | 4.5 V to 17 V | 0 A to 12 A |
