AP1501A
150kHz, 5A PWM BUCK DC/DC CONVERTER
Description
The AP1501A series are monolithic ICs that are designed for a step-
down DC/DC converter, and possess the ability to drive a 5A load
without additional transistor component. Due to reducing the number
of external component, the board space can be saved easily. The
external shutdown function can be controlled by logic level and then
come into standby mode. The internal compensation makes feedback
control have good line and load regulation without external design.
Regarding protected function, thermal shutdown is to prevent over
temperature operating from damage, and current limit is against over
current operating of the output switch. The AP1501A series operates
at a switching frequency of 150kHz thus allowing smaller sized filter
components than what would be needed with lower frequency
switching regulators. Other features include a guaranteed
±4% tolerance on output voltage under specified input voltage and
output load conditions, and ±15% on the oscillator frequency. The
output version includes fixed 3.3V, 5V, 12V and an adjustable type.
The packages are available in a standard 5-lead TO263-5, TO220-5
and TO220-5 (R) packages.

大家好!我们用的是君正jz4740的CPU,由于JZ4740只有两个串口(已有用途),现在不够,用需要第三个串口,于是乎想用GPIO来模拟一个串口来通信,我的gpio模拟串口是用在终端通讯上的,要通过串口发送和接收少量的数据(比如我要拨打电话,就通过串口发送封装过好AT命令到有GPRS模块的终端上,或者接受来自GPRS终端上的数据),9600的波特率就可以。...
