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. The LTC is a V input-capable synchronous buck converter that delivers up to mA of continuous output current. Applications include point-of-load conversion from 12V or 5V inputs in telecom, industrial, avionics and test equipment. All pricing is for 1, piece quantities. Multiphase operation reduces input and output ripple as well as the datxsheet of input and output capacitors.

Applications include industrial and medical equipment, and networking and telecom systems. The LTC is a versatile mA high voltage buck-boost charge pump.

This device uses switched capacitor fractional conversion to maintain regulation over a wide range of input voltage from 2. With a VIN range of 4. Other IC features include low external parts count with ceramic capacitor stability, soft-start circuitry to prevent excessive current flow during startup, plus short circuit and thermal protection.

It is housed in a low height profile 4. For applications requiring large input-to-output differentials, the LT offers a very compact and thermally effective solution. These tiny external capacitors can be used without any necessary series resistance as is common with many other regulators. For applications that require the lowest possible noise, the LTC can be configured to run in pulse-skipping mode, reducing noise and potential RF interference.


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. To protect the load, the LTM features output overvoltage and overcurrent protection. The LTM converts input supplies ranging from 4. The combination of its thermally enhanced MSOP package and a constant switching frequency up to 3MHz enables the designer to balance printed circuit board solution size with required efficiency.

A user-programmable output current limit can set output current from 10mA to mA thereby minimizing the need to oversize external components and protecting high impedance sources.

It can deliver up to mA of continuous output current from each channel at output voltages as low as 0. The LTC accommodates an input voltage range of 4.

The LTC version offers eight fixed output voltages from 2. Internal protection circuitry includes reverse-battery protection, no reverse current, current limiting with foldback, and thermal limiting. The LTC’s unique constant frequency architecture with reduced switching edge rates provides lower conducted and radiated noise compared to conventional switching regulators. The LTC is available in a low-profile 0.

Internal circuitry automatically selects the conversion ratio 2: The constant 1MHz switching frequency ensures low noise and high efficiency, while minimizing the size of the external components.

Their constant frequency, current-mode architecture minimizes switching noise while offering very fast line and load transient response. Its peak current mode architecture offers excellent line and load datasheft response. Show Tabs Hide Tabs. With options for Burst Mode operation for the highest conversion efficiency at light load and pulse-skipping operation for lower output voltage ripple, gives users the option to personalize a circuit’s performance.

Systems designers value pin compatibility since they can interchange these products without layout changes at any stage from development to production.

Additional features include power datasheer voltage monitors, internal compensation, independent soft-start capability for each channel and short-circuit protection. The LTM features protection functions for overcurrent and overvoltage conditions and the internal temperature of the device can be monitored via an internal temperature sensing diode.

A frequency adjust pin permits the user to program the frequency between kHz and 1MHz, optimizing efficiency while minimizing external component size and cost offering a very compact HB LED driver or charger solution. Spread spectrum frequency modulation reduces EMI emissions, while an internal PMOS switch driver delivers robust short-circuit protection in boost and buck-boost topologies. The combination of its 2mm x 3mm DFN or MSOP-8 package high switching frequency and tiny, low cost capacitors and inductors ensures a highly compact solution footprint.
