BP5275-50

Data Sheet Non-Isolated Step-Down 3-Terminal DC/DC Converters BP5275-18 / BP5275-25 / BP5275-33 / BP5275-50 Description The BP5275 series of DC/DC converters utilize a synchronous rectification system. A control circuit, switching element, and coil are built in, along with input/output capacitors, resulting in stable operation with no external components required. High conversion efficiency, combined with an original heat dissipation structure, enables configuration an ultra-compact switching power supplies. 500mA output is possible with no heat sink required (800mA with heat sink). In addition, the ICs are pin-compatible with conventional TO-220 LDO regulators, making replacement easy. Low ripple voltage with high precision output ensure stable operation against the fluctuating voltages from main power supplies, making them ideal for use as local power supplies (i.e. for microcontrollers). Applications Power supplies for copiers, personal computers, facsimiles, AV equipment, measuring instruments, vending machines, security device, registers, industrial equipment, and maintenance tools Features 1) No external parts required 2) High power conversion efficiency. 3) Heat sink unnecessary. 4) Low output ripple voltage 5) High output voltage accuracy 6) Pin-compatible with conventional 3-pin LDOs 7) Compact package.
