Digital potentiometer programs and stabilizes voltage reference -
30-May-02 Issue of EDN The potentiometer portion of a mixed-signal,
digitally programmable potentiometer adds variability to an analog circuit, and
its digital controls provide programmability. You can use a digital
potentiometer in two ways in an analog circuit. You can use it as a two-terminal
variable resistance, or rheostat, or as a three-terminal resistive divider....

Direct Current Ignition Reference Design - This manual describes a
reference design of a Digital Direct Current Ignition for Motorbike by using the
MC68HC908JK3. The Motorola MC68HC908JK3 is a member of the HC08 Family of
microcontrollers (MCUs). It is a 8-bit low cost general purpose MCU with 16-bit
free run timer. The features of the MC68HC908JK3 include input capture and
output....(app note added 3/05)
Dual output LDO 250mA/500mA evaluator with load simulator -
TPS70151EVM-152 provides a convenient method for evaluating the performance of
TPS701xx dual output linear regulators. The EVM provides proven and demonstrated
reference designs and test modes to aid in evaluation. (added 3/05)
Efficient 100W Isolated Power Supply Reference Design using UCC3580-1 - This
reference design is an active-clamp forward converter that can deliver up to 30 A of
continuous current at 3.3 V from an input range of 35 V to 72 V. The active-clamp topology
with self-driven secondary synchronous MOSFETs allows the device to achieve high
efficiencies. The design includes remote sense connections for point-of-load regulation
and is footprint compatible with Half Brick Modules. (added 3/05)
Get buck-boost performance from a boost regulator - 11-Jul-02 Issue of EDN
The SEPIC (single-ended, primary-inductance-converter] topology is generally a good choice
for voltage regulators that must produce an on output voltage that falls in the middle of
the input-voltage range, such as a 5V output from a 2.7 to 6V input, The topology has some
disadvantages, however. The efficiency of a SEPIC circuit fares worse than that of buck
and boost regulators, and SEPIC desig.... [Design Idea by Tom Gross, Linear Technology
Corp, Milpitas, CA]
Luxeon for Camera Phone Flash PDA & DSC Applications - This reference design
outlines the key considerations in the construction of a solid state, high performance
flash solution utilizing Luxeon LED technology. This design integrates Lumileds’
high power Luxeon Emitters product with a cost effective lens solution to provide the
necessary light output....(added 3/05)
NiMH Battery Charger Reference Design - This manual describes a reference design
for a NiMH battery charger that uses the Motorola MC68H(R)C908JK3E MCU. The
MC68H(R)C908JK3E includes a 10-channel Analog-to-Digital Converter (ADC) and a 2-channel
Timer Module which can be programmed to....(app note added 3/05)
