LED Driver IC with TRIAC Dimming

LED Driver IC with TRIAC Dimming, Single-Stage PFC and 
Primary-Side Constant Current Control  


The LinkSwitch-PH dramatically simplifies implementation of LED
drivers requiring PF >0.9, TRIAC dimmer capability and high efficiency.

The single-stage PF and constant current controller eliminates passive circuitry required for power factor correction and electrolytic bulk capacitor.

The advanced primary-side control techniques used by the LinkSwitch-PH device provide accurate constant current control while eliminating the need for an
optocoupler and secondary-side current control circuitry.

LinkSwitch-PH incorporates a 725 V power MOSFET, a continuous-mode PWM controller, a high voltage switched current source for self biasing, frequency jittering, cycle-by-cycle
current limit and hysteretic thermal shutdown circuitry, all in a monolithic IC.

Basic DAC Architecture

Basic DAC Architectures I: String DACs an Thermometer (Fully Decoded) DACs by Walt Kester 

Rather than simply treating DACs as black boxes having a digital input and an analog output, it 

is much more useful to understand the fundamental DAC architectures in use today. This can 

also aid in the selection process which can be somewhat daunting considering the sheer number 

of DACs currently on the market.  

 

This tutorial examines the most fundamental DAC architectures, the "string" DAC and the 

"thermometer" DAC. String DACs had their origin with Lord Kelvin, who invented the Kelvin 

divider in the mid-1800s. String DACs are popular today, especially in applications such as 

digital potentiometers where resolutions of 6 to  8 bits are typical. Because of their relative 

freedom from code-dependent switching glitches, thermometer DACs are popular building 

blocks in low distortion segmented DACs as well as in pipelined ADCs. More TUTORIAL

MX25L1606E and MX25L8006E feature

This  application  note  indicates  the  differences  between  MX25L1606E  &  MX25L8006E  and MX25L1605D & MX25L8005.

The information provided is based on the data available at the time. The MX25L1606E & MX25L8006E datasheet  may  override  this  application  note  is  there  is  a  difference  description  for  the  same  in  the datasheet.

Macronix is introducing the “E” revision, the next generation of 8Mb/16Mb serial flash
products on our existing 0.11um technology.

In Single I/O mode, the MX25L8006E and MX25L1606E are identical in forms and
functions with the MX25L8005 and MX25L1605D. The MX25L8006E and MX25L1606E
are also capable of Single Input / Dual Output mode. However, the MX25L1606E no
longer supports Dual Input / Dual Output and Continuously Program (CP) Mode. Please
see table on page 2 for additional feature comparisons.

MX25L8005 and/or MX25L1605D need to migrate to the MX25L8006E and/or
MX25L1606E. New design should only adopt the new products. Migrating to these
new products will enable Macronix to provide continuous support to our customers.
