Smart Regulator Series 7 to 26V Input, 1.0A, Fixed Output Voltage 3 terminals DC/DC Regulator BP5293-xx Series General Description Key Specifications The BP5293-xx series is one packaged 3terminals Buck Input Voltage Range: (BP5293-33): 7~26V type DC/DC Converter built-in all parts of DC/DC (BP5293-50): 7~26V converter. (BP5293-12): 17~26V High efficiency compared with 3 terminals regulator, and Output Decision Voltage:(BP5293-33): 3.3V3% not necessary to heat sink. Its able to rearrange without (BP5293-50): 5.0V2% redesign PCB, because of pin compatible. The built in (BP5293-12): 12V5% input/output capacitors and coil is contribute to compact Maximum Output Current: 1A (Max.) design. Operation Temperature Range: -25~85 Supplied DC30Vmax output fixed voltage which is 3.3V, 5.0V, 12.0V line up. The output max current is 1A. High efficiency at light load with a SLLMTM. It is most suitable for use in the equipment to reduce the standby power is required.
