摘要

在本文中，我们提出了一个小尺寸升压型DC-DC变换器模块与微型嵌入式电感。该变换器模块由一个内置开关器件和电感的升压变换器控制器集成芯片组成，只需要两个电容器作为外部部件。因此，它具有与降压变换器的串联稳压器相同的可用性。提出的升压型DC-DC转换器由2.4 mm(类型)× 2.4 mm(类型)× 0.9 mm(最大)尺寸8引脚SON(小轮廓非引线)封装组成。所提出的升压型DC-DC转换器的电源电压由单个锂离子电池输入(如蜂窝电话)的应用确定。所提出的原型DC-DC变换器效率高达93%。

Small-size boost type DC-DC converter with the tiny embedded inductor

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%.
