explain
Tps56c230 is an efficient synchronous buck converter equipped with integrated FET. System designers can use this device in various applications because of its low standby current and less external components.
Tps56c230 adopts d-cap3 control, which can realize fast transient response and excellent line and load adjustment only by internal compensation. The device has a dedicated circuit that supports low equivalent series resistance (ESR) output capacitors (such as dedicated polymer capacitors and ultra-low ESR ceramic capacitors).
The mode pin of tps56c230 can be used to set eco mode or FCCM mode to realize light load operation. Eco mode can maintain high efficiency during light load operation, and FCCM mode operation can maintain low output ripple under light load. This device supports both internal and external soft start time options. It has an internal fixed soft start time of 1.2ms, but if the application requires a longer soft start time, it can be realized by using the external SS pin and connecting the external capacitor.
Tps56c230 integrates the normal state indicator of power supply and has the function of output discharge. It provides comprehensive protection including OVP, UVP, OCP, OTP and UVLO. The device can use 20 pin 3.0mm × 3.0mm hotrod package with rated junction temperature range of – 40 ° C to 125 ° C.
