It is housed in a low height profile 4. The LTM permits output voltage tracking for sequencing multiple rails in a system.

Low operating current 18? Additionally it offers current both input and output current limiting and monitoring for added reliability and design flexibility. The low datasheer 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. Other features include a power good indicator, current-mode datsheet, internal compensation thermal shutdown and output disconnect.

It also includes programmable maximum power point control MPPC capability, ensuring maximum power extraction from non-ideal power sources such as photovoltaic cells. The LTC is a high efficiency, 2. Applications include industrial and medical equipment, and networking and telecom systems. 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.

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 accommodates an input voltage range of 4.

This device uses switched capacitor fractional conversion to maintain regulation over a wide range of input voltage from 2. Show Tabs Hide Tabs. Quiescent current of only 1. Robust open and short-circuit protection maximize overall system reliability. Internal circuitry automatically selects the conversion ratio 2: Multiphase operation reduces input and output ripple as well as the number of input and output capacitors.

The two channels run degrees out of phase, minimizing the size of input capacitance. 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. The LTM converts input supplies ranging from 4. These tiny external capacitors can be used without any necessary series resistance as is common with many other regulators.

The constant 1MHz switching frequency ensures low noise and high efficiency, while minimizing the size of the external components. For less demanding dimming requirements, the CTRL pin can be used to offer a For applications requiring large input-to-output differentials, the LT offers a very compact and thermally effective solution. 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.


The combination of its MSOP package with only three tiny externals provides a highly compact solution footprint for a broad range of applications. 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.

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

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. 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. Internal protection circuitry includes reverse-battery protection, no reverse current, current limiting with foldback, and thermal limiting. Four devices in parallel can deliver 80A of load current. The LTC can be programmed with fixed output voltages of 1.

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.
