TPS56C231

3.8-V to 17-V, 12-A synchronous buck converter with D-CAP3 control; ? 4.5-V to 17-V input range without external bias\n? 3.8-V to 17-V input range with external bias\n? Supports 12-A continuous output current\n? TPS56C231 supports 15-A peak current\n? Integrated 7.8-mΩ and 3.2-mΩ MOSFETs\n? 0.6-V ±1% reference voltage across a –40°C to 125°C junction temperature range\n? 0.6-V to 5.5-V output voltage range\n? 146-μA low quiescent current\n? D-CAP3? control mode for fast transient response\n? Supports ceramic output capacitors\n? Selectable fSW of 400 kHz, 800 kHz, and 1200 kHz\n? Selectable FCCM (forced continuous conduction mode) for tight output voltage ripple \n? Selectable Eco-mode (auto skip mode) for high light-load efficiency\n? Optional external 5-V bias for enhanced efficiency\n? Prebiased start-up capability\n? Adjustable soft start with a default 1.2-ms soft-start time\n? Power-good indicator to monitor output voltage\n? Two adjustable current limit settings with hiccup restart: TPS56C231 (14.7 A, 17 A) and TPS56C231L (11.5 A, 13.8 A)\n? Non-latched protections for UV, OV, OT, and UVLO\n? Pin-to-pin compatible with 12-A TPS56C215, and 8-A TPS568231 and TPS568215 \n? –40°C to 125°C operating junction temperature\n? 3.5-mm × 3.5-mm, 18-pin HotRod? QFN package;

The TPS56C231 is a small, high-efficiency, synchronous buck converter with an adaptive on-time D-CAP3 control mode. Because external compensation is not required, the device is easy to use and requires few external components. The device is well-suited for space-constrained data center applications.\n\nThe TPS56C231 has competitive features including a very accurate reference voltage, fast load transient response, and no requirement for external compensation, adjustable current limit, and both Eco-mode and FCCM operation modes for selection at light-load condition through the configuration of the MODE pin. To attain high efficiency at light load, Eco-mode can be selected. To support tight output voltage ripple requirement, FCCM can be selected. The TPS56C231 operates from a –40°C to 125°C junction temperature range.
