Rohm presents its new high voltage resistance, high efficiency DC/DC Converter module BP5277 family which eliminates the need of external components and thermal design. Configuring a DC/DC converter used to be complicated and time-consuming, starting with the selection of ICs for the loads and covering circuit design as well as the selection of constants e.g. those for phase compensation, board design for obtaining desired characteristics, and thermal design for heat generation. This new 3-pin DC/DC converter module integrates all required components such as the control circuit, switching element, coil as well as I/O capacitors and also allows for high-power operation. Since the series can be deployed like a module, all necessary characteristics can be obtained without involving circuit and board design which significantly reduces the time, costs and energy required for the power supply design.

Based on an identical configuration, and including pin compatibility to the max. 15V series, the new family features a max. 36V input voltage converter module, which allows for applications with larger equipment. While providing high input voltage, the new BP5277 series also facilitates high energy-savings. Besides a high efficiency conversation ratio of up to 93% (for 24V -> 15V), it achieves high output voltage accuracy of ±2%. The line-up includes six different output voltage types (3.3V/5.0V/9.0V/12.0V/13.0V/15.0V), making it possible to select the ideal solution based on individual specifications.

With particular attention paid to heat dissipation performance, the BP5277 Series considerably minimizes required mounting area. A heat sink is mounted on the back of the module and combined with a special structure that dissipates heat directly from the heating element, eliminating the need for thermal design. This enables a maximum output current of 500mA without requiring any external heat sink while mounting a heat sink permits a maximum output current of 800mA.
The BP5277 family is perfect for use in a broad range of applications such as Power conditioners, gaming devices, office equipment, measurement devices, industrial equipment, and major appliances, including gas water heaters, washing machines, refrigerators, and air conditioners.
