3 terminal DC/DC smart regulator

The BP5293-50 is one packaged 3-terminals Buck type completely integrated DC/DC Converter. This high efficiency 3-terminal regulator does not need a heat sink. Since it is pin compatible to the 3-terminal regulators, there is no need for PCB re-design to use this integrated DC/DC converter. With built-in input/output capacitors and coil makes this a compact design.

BP5293-50 is a synchronous rectifying switching regulator that achieves faster transient response by employing current mode PWM (Pulse Width Modulation) control system. It utilizes switching operation for 570kHz (typ.) in PWM mode for heavier load, while it utilizes SSLMTM (Simple Light Load Mode) control for lighter load to improve efficiency. While in this mode, the switching function is stopped and it outputs waveform of output voltage.

This integrated DC/DC converter comes with a wide input voltage range of 7V to 26V and fixed 5.0V output. The output max current is 1A. Provides High efficiency at light load with a SLLMTM. It is most suitable for use in the equipment to reduce the standby power is required.
