Demonstration circuit 1999A is a fixed frequency synchronous buck-boost converter with an extended input and output range. The unique 4-switch, single inductor architecture provides low noise and seamless operation from input voltages above, below, or equal to the output voltage. Typical demo board efficiency is shown in Figure 2 for several loads. The demo board has the provision to set an accurate run threshold. Consult the LTC3111data sheet for more information. The transient response of the converter to a 100mA to 600mA transient at input voltages of 3.5V and 12V are presented in Figures 3 and 4. The LTC®3111 features selectable PWM or Burst Mode® operation, and an easily synchronizable oscillator. Jumper JP1 is provided to enable the converter. The demo board is configured for 800kHz. A jumper, JP2, is provided to select PWM, or Burst Mode operation. A clock signal can also be applied to JP2 if synchronization is desired. The LTC3111 data sheet has detailed information about the operation, specifications, and applications of the part. The data sheet should be read in conjunction with this Quick Start Guide. The LTC3111 operates with a 2.5V to 15V input voltage range and a VOUT range from 2.5V to 15V. The demonstration board has been designed to operate with VIN from 2.5V to 15V and an output current up to 1.5A. For VIN < 5V, IOUT capability is reduced. VOUT is set to 5.0V.
