Overview

Package  

The BM2P Series was designed for use in AC adapters, home appliances, office equipment, and the like. A low ON resistance super junction MOSFET is built in for significantly improved efficiency, ensuring compliance with the latest Energy Star* standard. Delivers an optimized power supply system for sets of all types.

*:An international environmental leveling system for energy saving in OA equipment

Feature 1 : Complies with the latest international standards for efficiency 

■Class-leading efficiency
自社スーパージャンクションMOSFET採用で大きく省エネ化!

For 25W adapters, simply replacing the IC itself will boost efficiency to over 87% (compared with sub-87% with conventional products). This can be increased to over 90% by optimizing the circuit (including selecting the right peripheral components). As a result, the ICs easily pass the new EnergyStar 6 requirements for efficiency.

■Significantly lower standby power consumption
自社スーパージャンクションMOSFET採用で大きく省エネ化!

Power consumption during standby with a 25W adapter is less than 20mW at 100VAC and less than 30mW at 230VAC - well below the 100mW requirement set by the Energy Star 6 standard. And further improvements are possible through circuit optimization.

Feature 2 : Compact surface mount package added to the lineup

With planar-type MOSFETs commonly used in AC/DC applications, miniaturization is typically difficult due to problems associated with heat dissipation. In contrast, adopting a super junction MOSFET allows for a more compact IC design, including a small surface mount SOP8 package to complement the standard DIP7 type. The SOP8 form factor reduces mounting area by 47% over conventional models.
