Demonstration circuit 761 is a low noise regulated charge pump featuring the LTC3204 (Burst Mode operation) in the 2X2 DFN package. There are two assembly versions, DC761A-A and DC761A-B for the LTC3204-5 (5V output) and LTC3204-3.3 (3.3V output) respectively. The DC761A-A produces a regulated 5V output from a 2.7V to 5.5V input. The guaranteed output load current is 150mA for VIN between 3.1V and 5.5V, and 65mA for VIN less than 3.1V. The DC761A-B produces a regulated 3.3V output from a 1.8V to 4.5V input. The guaranteed output current is 50mA from VIN between 1.9V and 4.5V, and 40mA for VIN less than 1.9V. The circuit requires only three tiny 0603 surface mount capacitors and uses minimal board space. No inductor or diodes are needed. The circuit features automatic Burst Mode® operation at light loads to maintain low supply current.

Demonstration Circuit 767 is an I2C-controlled high efficiency synchronous current mode buck regulator featuring the 600mA output LTC3447. The demo board input voltage range is 2.5V to 5.5V. The buck regulator has a programmable output range of 0.7V to 2.00V which is set with an internal 6-bit DAC via the I2C interface. The initial start-up voltage is set to 1.35V but can be change by changing feedback resistors R4 and R5.

Demonstration circuit DC770C is a 2-phase DC/DC boost converter featuring the LT3782A constant frequency current mode boost controller. The DC770C operates over 10V to 28V input and provides 4A of output current at 50V output. The 250kHz constant frequency operation results in a small and efficient circuit.

The AD7991?/ AD7995 /?AD7999 are 12-/10-/8-bit, low power, successive approximation ADCs with an I2C?-compatible interface. Each part operates from a single 2.7 V to 5.5 V power supply and features a 1 ?s conversion time. The track-and-hold amplifier allows each part to handle input frequencies of up to 14 MHz, and a multiplexer allows taking samples from four channels.Each AD7991 / AD7995 / AD7999 provides a 2-wire serial interface compatible with I2C interfaces. The AD7991 and AD7995 come in two versions and each version has an individual I2C address. This allows two of the same devices to be connected to the same I2C bus. Both versions support standard, fast, and high speed I2C interface modes. The AD7999 comes in one version.The AD7991 / AD7995 / AD7999?normally remain in a shutdown state, powering up only for conversions. The conversion process is controlled by a command mode, during which each I2C read operation initiates a conversion and returns the result over the I2C bus.When four channels are used as analog inputs, the reference for the part is taken from VDD; this allows the widest dynamic input range to the ADC. Therefore, the analog input range to the ADC is 0 V to VDD;. An external reference, applied through the VIN3/VREF input, can also be used with this part.PRODUCT HIGHLIGHTS Four single-ended analog input channels, or three single-ended analog input channels and one reference input channel.
