The LT1931AES5#TRMPBF is an inverting DC/DC converter from LT, part of the LT1931/LT1931A series. This device operates at a fixed frequency of 1.2MHz or 2.2MHz, enabling the use of small surface mount components. It supports a wide input voltage range from 2.6V to 16V and is capable of generating negative output voltages with low ripple.
Key electrical specifications include a typical feedback voltage of -1.255V and a low shutdown current of less than 1µA. The integrated switch has a low VCESAT of 400mV at 1A, and the device can handle a switch voltage rating of up to 36V.
This converter is available in a low profile (1mm) ThinSOT-23-5 package, suitable for space-constrained applications. Its design is pin-for-pin compatible with the LT1611, offering an upgrade path for higher power requirements.
Typical applications include disk drive MR head bias, digital camera CCD bias, LCD bias, and GaAs FET bias, providing a local low noise, low impedance negative supply.
