Its constant switching frequency of 2. Low operating current 18? Show Tabs Hide Tabs. With a VIN range of 4. Systems designers value pin compatibility since they can interchange these products without layout changes at any stage from development to production. Additionally it offers current both input and output current limiting and monitoring for added reliability and design flexibility.

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.

Quiescent current of only 1. The LTC is a versatile mA high voltage buck-boost charge pump. The output voltage can be set with one resistor from 0. The LTC is a V input-capable synchronous buck converter that delivers up to mA of continuous output current. 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 electrical specifications are identical to the existing E- and I-grade versions of this device. 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. All pricing is for 1, piece quantities. The combination of its MSOP package with only three tiny externals provides a highly compact solution footprint for a broad range of applications.

It operates from an input voltage range of 4. Four devices in parallel can deliver 80A of load current.

For applications requiring large input-to-output differentials, the LT offers a very compact and thermally effective solution. Its fixed frequency, current mode architecture offers stable operation over a wide range of supply and output voltages. The LTC accommodates an input voltage range of 4.

The constant 1MHz lm1136 frequency ensures low noise and high efficiency, while minimizing the size of the external components. 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 can be programmed with fixed output voltages of 1.

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 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 LTC is available in a low-profile 0. 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. The LTC is a synchronous buck-boost converter that delivers up to mA of continuous output current from a wide variety of input datashee including single or multiple-cell batteries as well as solar panels and supercaps.


These tiny external capacitors can be used without any necessary series resistance as is common with many other regulators. 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.

The Llm136 utilises internal synchronous rectification and a programmable peak current-mode design to optimize efficiency over dtasheet broad range of output currents.

Their constant frequency, current-mode architecture minimizes switching noise while offering very fast line and load transient response. 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 vatasheet.

Internal circuitry automatically selects the conversion ratio 2: It can deliver up to mA of continuous output current from each channel at output voltages as low as 0.
