The LTC is a versatile mA high voltage buck-boost charge pump. 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 LTC utilises internal synchronous rectification and a programmable peak current-mode datasheeh to optimize efficiency over a broad range of output currents. The combination of its MSOP package with only three tiny externals provides a highly compact solution footprint for a broad range of applications. Internal circuitry automatically selects the conversion ratio 2: 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.

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 LTC version offers eight fixed output voltages from 2.
Robust open and short-circuit protection maximize overall system reliability. The LTM permits output voltage tracking for sequencing multiple rails in a system. The LTC’s unique constant frequency architecture with reduced switching edge rates provides lower conducted and radiated noise compared to conventional switching regulators.
Internal protection circuitry includes reverse-battery protection, no reverse datashet, current limiting with foldback, and thermal limiting. It also includes programmable maximum power point control MPPC capability, ensuring maximum power extraction from non-ideal power sources such as photovoltaic cells.
Their constant frequency, current-mode architecture minimizes switching noise while offering very fast line and load transient response.

Applications include point-of-load conversion from 12V or 5V inputs in telecom, industrial, datqsheet and test equipment. The constant 1MHz switching frequency ensures low noise and high efficiency, while minimizing the size of the external components.
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. The low noise buck-boost topology datashet 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.
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. 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.
Applications include industrial datasheett medical equipment, and lm1136 and telecom systems. Additionally it offers current both input and output current limiting and monitoring for added reliability and design flexibility.
It can deliver up to mA of continuous output current from each channel at output voltages datassheet low as 0. For less demanding dimming requirements, the CTRL pin can be used to offer a The LTC is available in a low-profile 0.
It is housed in a low height profile 4. The two channels run degrees out of phase, minimizing the size of input capacitance.
Systems designers value pin compatibility since they can interchange these products without layout changes at any stage from development to production. 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.
