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.
