LM136-2.5 Datasheet

This H-grade version is ideal for automotive, industrial and military applications that are subject to high ambient temperatures. The LTC accommodates an input voltage range of 4. 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.

Its constant switching frequency of 2. The LTC is a high efficiency, 2. Multiphase operation reduces input and output ripple as well as the number of input and output capacitors. The LTC’s unique constant frequency architecture with reduced switching edge rates provides lower conducted and radiated noise compared to conventional switching 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.

Applications include point-of-load conversion from 12V or 5V inputs in telecom, industrial, avionics and test equipment. It is housed in a low height profile 4. This device uses switched capacitor fractional conversion to maintain regulation over a wide range of input voltage from 2.

For applications requiring large input-to-output differentials, the LT offers a very compact and thermally effective solution.

The combination of its thermally enhanced MSOP package and a constant switching frequency up to 3MHz enables the designer to balance printed datasheett board solution size with required efficiency.

The LTC utilises internal synchronous rectification and a programmable peak current-mode design to optimize efficiency over a broad range of output currents.

The LTC is a synchronous buck-boost converter that delivers up to mA of continuous output current from a wide variety of input sources including single or multiple-cell batteries as well as solar panels and supercaps. The combination of its MSOP package with only three tiny externals provides a highly compact solution footprint for a broad range of applications.

The LTM features protection functions for overcurrent and overvoltage conditions and the internal temperature of the device can dtasheet monitored via an internal temperature sensing diode. The LTC is a high efficiency, 17V input capable synchronous buck regulator that delivers up to 1A of continuous output current to outputs as datadheet as 0.

The LTM converts input supplies ranging from 4.

Additionally it offers current both input and output current limiting and monitoring for added reliability and design flexibility. To protect the load, the LTM features output overvoltage datasyeet overcurrent protection. A user-programmable output current limit can set output current from 10mA to mA thereby minimizing datashret need to oversize external components and protecting high impedance sources.

For less demanding dimming requirements, the CTRL pin can be used to offer a These tiny external capacitors can datashedt used without any necessary series resistance as is common with many other regulators. A with no load, 4? The LTC can be programmed with fixed output voltages of 1. Additional features include power good voltage monitors, internal compensation, independent soft-start capability for each channel and short-circuit protection.

The LTC is a versatile mA high voltage buck-boost charge pump. Their constant frequency, current-mode architecture minimizes switching noise while offering very fast line and load transient response.

Low operating current 18? With a VIN range of 4. Its fixed frequency, current mode architecture offers stable operation over a wide range of supply and output voltages. 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. Four devices in parallel can deliver 80A of load current.

Systems designers value pin compatibility since they can interchange these products without layout changes at any stage from development to production. 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 two channels run degrees out of phase, minimizing the size of input capacitance.

Internal protection circuitry includes reverse-battery protection, no reverse current, current limiting with foldback, and thermal limiting. It can deliver up to mA of continuous output current from each channel at output voltages as low as 0.
