The LT1931AES5#TRPBF is a high-performance inverting DC/DC converter designed for applications requiring low noise and compact size. It operates at fixed frequencies of 1.2MHz or 2.2MHz, allowing the use of small surface mount components. The device can generate -5V at 350mA or -12V at 150mA from a 5V input, with a wide input voltage range of 2.6V to 16V. It features very low output ripple of 1mVP-P and a low shutdown current of less than 1¬µA. The LT1931AES5#TRPBF is pin-for-pin compatible with the LT1611, making it suitable for easy upgrades in existing designs. The device is housed in a low-profile 5-lead ThinSOT package, making it ideal for space-constrained applications such as disk drives, digital cameras, and LCD biasing. The operating temperature range is -40¬8C to 85¬8C, ensuring reliability in various environments.
