The APW7008 is
a high efficiency charge pump white LED driver;
the device drives up to four white LEDs with
regulated constant current for uniform
intensity. The supply voltage ranges from 2.7V
to 5.5V and it is optimized for a Li-ion battery
application. The APW7008 operates in 1x, 1.5x
and 2x charge pump modes and automatically
switches the charge pump modes depend on the
input voltage to maintain the required power for
high power efficiency. The APW7008 provides up
to 30mA per LED, for a total of 120mA and allows
several methods such as a PWM signal on the
CTRL0 pin for LED dimming. Three control logic
pins allow to disable or enable a combination of
LEDs. The supply current is only 2mA in 2x mode,
and the EN pin allows the device to enter
shutdown mode with 2uA quiescent current. The
APW7008 switches at 1MHz frequency and only
requires four 1uF ceramic capacitors and one
resistor, and ensures low input current ripple
and EMI. The APW7008 is available in a 16-pin
QFN package. |

The APW
7136A/B/C is a current-mode and fixed frequency
boost converter with an integrated N-FET to
drive up to 8 white LEDs in series.
The series connection allows the LED current to
be identi ca l fo r un ifo rm b ri gh tn es s.
It s lo w on -resi st an ce o f N-FET and
feedback voltage reduce power loss and achieves
high efficiency. Fast 1MHz current-mode PWM
operation is available for input and output
capacitors and a small inductor while m inim
izing ripple on the input supply. The OVP pin
monitors the output voltage and stop switching
if exceeds the over-voltage threshold. An
internal soft-start circuit eliminates the
inrush current during start-up.
The APW7136A/B/C also integrates under-voltage
lockout, over-temperature protection and current
limit circuits. The APW 7136/A/B/C is available
in a SOT-23-6 package. |

FAN6300是一个高度集成的PWM控制器提供了几种特性，以增强表现反激式转换器。内置高压启动电路，可提供更多的启动电流，以加快启动的时间。
有一个内部电压检测器可以确保电力系统运作，在广泛的范围电压和任何负荷的情况下，也可以减少开关MOSFET的的损耗。一旦电源电压超过，则高压启动功能，将立即得到更好的功率消耗。
FAN6300一个专有的绿色模式功能提供关断时间调制，以减少开关频率，也延长电压开关，以保持最小开关电压，以尽量减少待机电消耗及轻载效率。
FAN6300控制器还提供了许多保护功能，当短路发生时，脉冲电流将被限制，以确保固定峰值电流准位，一旦断路故障发生在反馈环路，内部保护电路将禁用的PWM输出立即。 |
