LTC1474CMS8-5 | Low Q-Current High Efficiency Switching Regulator, 5V Fixed @ 300mA
Analog Devices Inc.
The LTC1474/LTC1475 series are high efficiency step-down converters with internal P-channel MOSFET power switches that draw only 10?A typical DC supply current at no load while maintaining output voltage. The LTC1474 uses logic-controlled shutdown while the LTC1475 features pushbutton on/off. The low supply current coupled with Burst Mode? operation enables the LTC1474/LTC1475 to maintain high efficiency over a wide range of loads. These features, along with their capability of 100% duty cycle for low dropout and wide input supply range, make the LTC1474/LTC1475 ideal for moderate current (up to 300mA) battery-powered applications. The peak switch current is user-programmable with an optional sense resistor (defaults to 325mA minimum if not used) providing a simple means for optimizing the design for lower current applications. The peak current control also provides short-circuit protection and excellent startup behavior. A low-battery detector that remains functional in shutdown is provided . The LTC1474/LTC1475 series availability in 8-lead MSOP and SO packages and need for few additional components provide for a minimum area solution.Applications Cellular Telephones and Wireless Modems 4mA to 20mA Current Loop Step-Down Converter Portable Instruments Battery-Operated Digital Devices Battery Chargers Inverting Converters Intrinsic Safety Applications

LTC3614EUDD Demo Board | 4A, 4MHz Monolithic Synchronous Step-Down DC/DC Converter
Analog Devices Inc.
Demo Circuit 1467 is a high efficiency, high frequency step-down converter, incorporating the LTC3614 monolithic synchronous regulator. The DC1467A has an input voltage range of 2.25V to 5.5V, and is capable of delivering up to 4A of output current. The output voltage of the DC1467A can be set as low as 0.6V, the reference voltage of the LTC3614. The operating frequency range of the DC1467A is either set to a fixed 2.25 MHz by connecting the frequency pin to SVin, set by an external resistor, or synchronized to an external clock, with a range up to 4 MHz. At low load currents, the DC1467A can operate in either noise sensitive applications, due to the capability of the LTC3614 to operate in pulse-skipping mode, or in high efficiency applications, because the LTC3614 also has Burst-Mode capability. The Burst Mode clamp can be set externally.

LTC3833EFE Demo Board | VIN = 4.5V to 24V, VOUT1 = 1.5V @ 15A, Inductor DCR Sensing, 89.4% Efficiency
Analog Devices Inc.
Demonstration circuit 1516A is a 1.5V/15A synchronous buck converter operating with a switching frequency of 300kHz over an input voltage range of 4.5V to 24V. The demo board comes in two versions. The -A version uses inductor DCR current sensing with an iron powder inductor for highest efficiency. The -B version uses a 2.5mΩ/1% sense resistor for accurate current sensing with a low DCR ferrite inductor. The fixed on-time valley current mode control of the LTC3833 allows for a fast load step response.
