Features for the TPS56C230 Input voltage range: 4.5 V to 18 V Output voltage range: 0.6 V to 5.5 V Supports 12-A continuous output current D-CAP3™ architecture control for fast transient response ±1% feedback voltage accuracy (25°C) Integrated 17-mΩ and 5.9-mΩ FETs Selectable Eco-mode™ and Forced Continuous Conductive Mode (FCCM) by MODE pin 500-kHz switching frequency Adjustable soft-start time with default 1.2 ms Integrated Power Good indicator Description for the TPS56C230 The TPS56C230is a high efficiency synchronous buck converter with integrated FETs. System designers can use the device in a wide variety of applications since it draws low standby current and requires few external components. The TPS56C230 employs D-CAP3 control that provides fast transient response and excellent line and load regulation with internal compensation. It also has a proprietary circuit that enables the device to support low equivalent series resistance (ESR) output capacitors such as specialty polymer and ultra-low ESR ceramic capacitors. TPS56C230‘s MODE pin can be used to set Eco-mode or FCCM mode for light-load operation.Eco-mode maintains high efficiency during light load operation, and FCCM mode operations keeps output ripple small at light load. The device supports both internal and external soft-start time option. It has an internal fixed soft-start time 1.2 ms, but if the application needs a longersoft-start time, the external SS pin can be used to achieve it by connecting a externalcapacitor. The TPS56C230 integrates power good indicator and provides output discharge function. Improvised complete protection including OVP, UVP, OCP, OTP and UVLO. The device is available in a20-pin 3.0-mm x 3.0-mm HotRod package and the junction temperature is specified from –40°C to125°C.
