The combination of its MSOP package with only three tiny externals provides a highly compact solution footprint for a broad range of applications. The constant 1MHz switching frequency ensures low noise and xatasheet efficiency, while minimizing the size of the external components. Other features include a power good indicator, current-mode control, internal datashdet thermal shutdown and output disconnect. The LTM permits output voltage tracking for sequencing multiple rails in a system.
Multiphase operation reduces input and output ripple as well as the number of input and output capacitors.
It is housed in ml136 low height profile 4. The low noise buck-boost topology provides a continuous transition through all of datasheett 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.
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.
