Spread spectrum frequency modulation reduces EMI emissions, while an internal PMOS switch driver delivers robust short-circuit protection in boost and buck-boost topologies. Robust open and short-circuit protection maximize overall system reliability. The LTC accommodates an input voltage range of 4. The low noise buck-boost topology provides a continuous transition through all of the operating modes, making it ideal for applications that must maintain a constant output voltage, even as the input source voltage transitions through the output voltage.
The output voltage can be set with one resistor from 0. The LTC is a high efficiency, 17V input capable synchronous buck regulator that delivers up to 1A of continuous output current to outputs as low as 0. The two channels run degrees out of phase, minimizing the size of input capacitance. A with no load, 4? This enables automatic correction of voltage errors caused by droop across PCB traces, which is valuable for powering loads such as FPGAs requiring high currents at low voltages.
The LTC is a high efficiency, 2. To protect the load, the LTM features output overvoltage and overcurrent protection. The LTC is a V input-capable synchronous buck converter that delivers up to mA of continuous output current. Additional features include power good voltage monitors, internal compensation, independent soft-start capability for each channel and short-circuit protection.
