Demonstration circuit 1526 is a monolithic step-down DC/DC switching regulator featuring the LT3991. The switching frequency is adjustable up to 2MHz. The demo circuit is designed for 3.3V, 1.2A output from a 4.5V to 55V input. The wide input range of the LT3991 allows a variety of input sources including automotive batteries and 24V industrial supplies. Low ripple Burst Mode increases the efficiency at the light load while keeping the output ripple below 15mV. The part is in shutdown when the EN pin is low and active when the pin is high. The threshold of the EN pin is accurate at 1.01V with 30mV of hysteresis. When VIN is above 6V, adding a resistor divider from VIN to EN can program the LT3991 to regulate the output only when VIN is above a desired voltage. The circuit consumes only 2.8μA of quiescent current. The boost diode, control and logic circuit are integrated to reduce the components count and solution size. The current mode control scheme creates fast transient response and good loop stability.

Demonstration circuit 1587A is a boost converter optimized for relatively high impedance, very low voltage input power sources. It allows a user to quickly evaluate the LTC3105 boost converter and LDO regulator. Capable of operating with an input voltage as low as 250mV and as high as 5V, the circuit features maximum power point control (MPPC). Jumpers on the circuit board allow the user to select several MPPC voltages, three boost output voltages and three LDO regulator output voltages. Also included are jumpers for shutdown and for selecting an external pull-up voltage for the power good status output. Terminals are provided for input and output connections, power good output and external power good supply input, shutdown input, and provisions for external MPPC resistor and MPPC diode input. This demonstration board is especially designed for low power solar cell applications.
