AP3015A中文资料boost-converter数据手册Diodes规格书

描述 Description

The AP3015/A are Pulse Frequency Modulation
(PFM) DC/DC converters. These two devices are functionally
equivalent except the switching current limit.
The AP3015 is designed for higher power systems
with 350mA current limit, and the AP3015A is for
lower power systems with 100mA current limit.
The AP3015/A feature a wide input voltage. The operation
voltage is ranged from 1.2Vto 12V (1V to 12V
for AP3015A). A current limited, fixed off-time control
scheme conserves operating current, resulting in
high efficiency over a broad range of load current.
They also feature low quiescent current, switching current
limiting, low temperature coefficient, etc.
Fewer tiny external components are required in the
applications to save space and lower cost.
Furthermore, to ease its use in differnet systems, a disable
terminal is designed to turn on or turn off the chip.
The AP3015/A are available in SOT-23-5 package.

简介

AP3015A属于集成电路（IC）的稳压器-DC-DC开关稳压器。由制造生产的AP3015A稳压器 - DC-DC 开关稳压器DC-DC 开关稳压器 PMIC（电源管理集成电路）产品族中的产品是元器件级设备，用于需要稳定 DC 输入电压和/或将其转换为不同幅度的输出电压的应用。这些器件与称为“控制器”PMIC 的类似产品的区别在于集成了主开关元件，设备提供的电力会通过该元件。
