The LTC7138 is a high efficiency step-down DC/DC regulator with internal power switch that draws only 12μA typical DC supply current while maintaining a regulated output voltage at no load.The LTC7138 can supply up to 400mA load current and features a programmable peak current limit that provides a simple method for optimizing efficiency and for reducing output ripple and component size. The LTC7138’s combination of Burst Mode® operation, integrated power switch, low quiescent current, and programmable peak current limit provides high efficiency over a broad range of load currents.With its wide input range of 4V to 140V and programmable overvoltage lockout, the LTC7138 is a robust regulator suited for regulating from a wide variety of power sources. Additionally, the LTC7138 includes a precise run threshold and soft-start feature to guarantee that the power system start-up is well-controlled in any environment. A feedback comparator output enables multiple LTC7138s to be connected in parallel for higher current

Demonstration circuit 2172A is a high input voltage, 400mA step-down regulator featuring the LTC7138. The output of the regulator can be programmed for either 5V, 3.3V or 1.8V with on-board jumpers or is adjustable from 800mV to VIN using an optional feedback divider. The input voltage range is from 4V to 140V. The LTC7138’s Burst Mode® operation, low quiescent current and internal top FET switch provide high efficiency over a wide range of loads. Other features include: • Optional components to adjust the current limit, make it proportional to VIN or improve the efficiency and reduce the output voltage ripple. • FBO turret to tie two or more LTC7138 regulators together if the application requires more load current. • Optional UVLO and OVLO divider. • External/internal soft-start. For more details, refer to the LTC7138 data sheet. The LTC7138 data sheet gives a complete description of the IC operation and application information. The data sheet must be read in conjunction with this quick start guide.
