The LM3478MMX/NOPB is a high-efficiency switching regulator with an adjustable output voltage. It is manufactured by Texas Instruments and is specifically designed for applications that require high output current, such as industrial equipment, telecommunication devices, and automotive systems.
The LM3478MMX/NOPB operates using a pulse width modulation (PWM) control scheme, allowing for precise regulation of the output voltage. It can accept input voltages ranging from 2.9V to 42V and is capable of providing an output voltage as low as 1.23V.
Some key features of the LM3478MMX/NOPB include an integrated low-side power MOSFET, which enables high efficiency and reduces overall system complexity. This IC also incorporates a built-in soft-start function that prevents excessive inrush current during startup, which is beneficial for sensitive components.
Furthermore, the LM3478MMX/NOPB offers a wide switching frequency range from 100 kHz to 1 MHz, allowing users to optimize their design based on specific requirements. It also features an adjustable current limit and an optional frequency synchronization input, which provides flexibility for various applications
