DC1232A: Demo Board for the LT3437 - High Voltage 500mA, 200kHz Step-Down Switching Regulator with 100µA Quiescent Current

The LTC3527/LTC3527-1 are dual high efficiency, step-up DC/DC converters in a space saving 16-lead 3mm ? 3mm QFN package. Battery life is maximized with a 700mV startup voltage and operation down to 500mV once started. The SHDN and PGOOD pins enable the converters to be sequenced or started together. The LTC3527/LTC3527-1 limit inrush current during startup. Selectable 1.2MHz or 2.2MHz operation provides a choice between the highest efficiency or smallest solution footprint. The current mode PWM design is internally compensated reducing external parts count. Burst Mode operation or fixed frequency operation is selectable via the MODE pin. Anti-ring circuitry reduces EMI in discontinuous mode. This device also features thermal shutdown. True output disconnect allows the output to be completely open in shutdown. The LTC3527-1 actively discharges VOUT1 or VOUT2 when its respective SHDN goes low. Quiescent current in shutdown is less than 2?A.Applications MP3/Personal Media Players Noise Canceling/Bluetooth Headsets Wireless Mice Portable Medical Instruments

The LT6106 is a versatile high side current sense amplifier. Design flexibility is provided by the excellent device characteristics: 250?V maximum offset and 40nA maximum input bias current. Gain for each device is set by two resistors and allows for accuracy better than 1%.The LT6106 monitors current via the voltage across an external sense resistor (shunt resistor). Internal circuitry converts input voltage to output current, allowing for a small sense signal on a high common mode voltage to be translated into a ground referenced signal. The low DC offset allows for monitoring very small sense voltages. As a result, a small valued shunt resistor can be used, which minimizes the power loss in the shunt.The wide 2.7V to 44V input voltage range, high accuracy and wide operating temperature range make the LT6106 ideal for automotive, industrial and power management applications. The very low power supply current of the LT6106 also makes it suitable for low power and battery operated applications.Applications Current Shunt Measurement Battery Monitoring Power Management Motor Control Lamp Monitoring Overcurrent and Fault Detection

Demonstration circuit 1248 is a dual monolithic buck regulator featuring the LT3509. The demo circuit is designed for 5V@700mA and 3.3V@700mA output from a 6.5V to 36V input. The input voltage can go up to 60V without damaging the part. The switching frequency can be set from 300kHz to 2.2MHz by a single external resistor, and it is synchronizable over the full range. The power switches, the compensation components and the boost diodes are all integrated into the silicon. The shutdown and soft start function is independent for each channel. The current mode control scheme creates fast transient response and good loop stability. The part has overvoltage lockout, cycle by cycle current limit and thermal shutdown. DA pin can further protect the silicon under fault conditions by sensing the diode current.
