Other features include a power good indicator, current-mode control, internal compensation thermal shutdown and output disconnect. These tiny external capacitors can be used without any necessary series resistance as is common with many other regulators. 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 l136 voltage transitions through the output voltage.
Multiphase operation reduces input and output ripple as well as the number of pm136 and output capacitors.

For less demanding dimming requirements, the CTRL pin can be used to offer a The combination of its MSOP package with only three tiny externals provides a highly compact solution footprint for a broad range of applications. It can deliver up to mA of continuous output current from each channel at output voltages as low as 0.
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 is a high efficiency, 2. The LTC version offers eight fixed output voltages from 2. Its constant switching frequency of 2. Their constant frequency, current-mode architecture minimizes switching noise while offering very fast line and load transient response.
The LTC is a V input-capable synchronous buck converter that delivers up to mA of continuous output current. Systems designers value pin compatibility since they can interchange dafasheet products without layout changes at any stage from development to production. The two channels run degrees out of phase, minimizing the size of input capacitance. It also includes programmable maximum power point control MPPC capability, ensuring maximum power extraction from non-ideal power sources such as photovoltaic cells.
Four devices in parallel can deliver 80A of load current. A with no load, 4? The LTC’s unique constant frequency architecture with reduced switching edge rates provides lower conducted and radiated noise compared to conventional switching regulators.
All pricing is for 1, piece quantities. 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.

Internal circuitry automatically selects the conversion ratio 2: Its peak current mode architecture offers excellent line and load transient response. The LTC is a versatile mA high voltage buck-boost charge pump. This H-grade version is ideal for automotive, industrial and military applications that are subject to high ambient temperatures. It operates from an input voltage range of 4.
For applications requiring large input-to-output differentials, the LT offers a very compact and thermally effective solution. The LTC can be programmed with fixed output voltages of 1. The LTM permits output voltage tracking for sequencing multiple rails in a system. Show Tabs Hide Tabs.
The LTC is available in a low-profile 0.
Internal protection circuitry includes reverse-battery protection, no reverse current, current limiting with foldback, and thermal limiting. 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. This device uses switched capacitor fractional conversion to maintain regulation over a wide range of input voltage from 2.
Low operating current 18? 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. The LTC utilises internal synchronous rectification and a programmable peak current-mode design to optimize efficiency over a broad range of output currents. To protect the load, the LTM features output overvoltage and overcurrent protection.
The electrical specifications are identical to the existing E- and I-grade versions of this device. The LTM converts input supplies ranging from 4. The constant 1MHz switching frequency ensures low noise and high efficiency, while minimizing the size of the external components.
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.
