STEP-UP, PWM CONTROL or PWM / PFM SWITCHABLE
BUILT-IN TRANSISTOR SWITCHING REGULATOR
S-8353/8354 Series
The S-8353/8354 Series is a CMOS step-up switching regulator which
mainly consists of a reference voltage source, an oscillation circuit, a
power MOS FET, an error amplifier, a phase compensation circuit, a PWM
control circuit (S-8353 Series) and a PWM / PFM switching control circuit
(S-8354 Series).
The S-8353/8354 Series can configure the step-up switching regulator with
an external coil, capacitor, and diode. In addition to the above features,
the small package and low current consumption make the S-8353/8354
Series ideal for portable equipment applications requiring high efficiency.
The S-8353 Series realizes low ripple, high efficiency, and excellent
transient characteristics due to its PWM control circuit whose duty ratio
can be varied linearly from 0 to 83% (from 0 to 78% for 250 kHz models),
an excellently designed error amplifier, and phase compensation circuits.
The S-8354 Series features a PWM / PFM switching controller that can
switch the operation to a PFM controller with a duty ratio is 15% under a
light load to prevent a decline in the efficiency due to the IC operating
current.
Features
• Low voltage operation: Startup at 0.9 V min. (I

= 1 mA) guaranteed
• Low current consumption : During operation 18.7

• Duty ratio : Built-in PWM / PFM switching control circuit (S-8354 Series)
15 % to 83 % (30 kHz and 50 kHz models)
15 % to 78 % (250 kHz models)
• External parts : Coil, capacitor, and diode

Applications
• Power supplies for portable equipment such as digital cameras, electronic notebooks, and PDAs
• Power supplies for audio equipment such as portable CD / MD players
• Constant voltage power supplies for cameras, VCRs, and communication devices
• Power supplies for microcomputers

坛里有用MRF24J40做ZIGBEE的吗?
准备用MRF24J40做ZIGBEE系统,MCU部分采用其他厂家的,问题在1、底层协议要自己编写,感觉没有头绪;2、MRF24J40通信距离大概是多少呢,之前的其他厂家距离都不是很远<100米。...

请问大侠们都用什么编写程序(不是调试编译)?
例如使用IAR或者CCS,没有智能提示。 看到说有好多用例如Source Insight,ultraedit之类的,但是想问一下,对于本征函数之类的怎么处理的?怎样让这些也智能提示?能不能说全面一点?...
