Abstract :
In this paper, we propose a small-size boost type DC-DC converter module with the tiny embedded inductor. The proposed converter module is composed with a boost converter controller IC chip with built-in switching devices and an inductor in one package, and it needs only two capacitors as external parts. Therefore it achieved the same usability as a series regulator of buck converter. The proposed boost type DC-DC converter is composed in 2.4 mm(typ.) by 2.4 mm(typ.) by 0.9 mm(max.) size 8 pin SON (small outline non-lead) package. The power supply voltage of the proposed boost type DC-DC converter is determined from applications of single lithium-ion cell inputs such as cellular phones. The proposed proto type DC-DC converter achieves high efficiency up to 93%.
