The LM2611AMFX/NOPB from Texas Instruments is a current mode, PWM inverting switching regulator designed for efficient power conversion. It features a Cuk topology, enabling it to produce a regulated negative output voltage from a wide input range of 2.7V to 14V.
Key electrical specifications include a switching frequency of 1.4MHz, a switch current limit of 1.2A, and a low quiescent current of 1.8 µA. The device offers a low output ripple of 1 mVp-p and can deliver up to 300 mA at -5V from a 5V input. It also features a low shutdown current of less than 1 µA, which helps conserve battery life when not in use.
This regulator is housed in a compact 5-pin SOT-23-5 package, suitable for surface mount applications. The operating temperature range is -40°C to 125°C (TJ). Its design utilizes input and output inductors for reduced ripple and RMS current, and a low R DS(ON) FET for high efficiency. The adjustable output voltage is set using a negative feedback pin with two resistors, and cycle-by-cycle current limiting simplifies its use.
The LM2611AMFX/NOPB is an ideal choice for applications requiring a regulated negative voltage rail with compact component size and good efficiency.
