TS922 is a dual-channel audio amplifier with low noise, low distortion, high output current and is suitable for audio devices, mobile phones, etc.

The L4962 is a monolithic power switching regulator that delivers 1.5A at a voltage variable from 5V to 40V in step-down configuration. Features of the device include current limiting, soft start, thermal protection, and 0 to 100% duty cycle for continuous operating mode.

TD350 is an advanced gate driver for IGBT and power MOSFET. Control and protection functions are included and allow the design of high reliability systems. Innovative active Miller clamp function avoids the need of negative gate drive in most applications and allows the use of a simple bootstrap supply for the high side driver TD350 includes a two-level turn-off feature with adjustable level and delay. This function protects against excessive overvoltage at turn-off in case of overcurrent or short-circuit condition. Same delay is applied at turn-on to prevent pulse width distortion. TD350 also includes an IGBT desaturation protection and a FAULT status output. TD350 is compatible with both pulse transformer and optocoupler signals.

TS971-TS972-TS974 are low noise operational amplifiers from TI with a working voltage range of 2.7V-10V. They feature extremely low noise and distortion, making them suitable for portable and battery-powered equipment.

The L5973D is a step-down monolithic power switching regulator with a minimum switch current limit of 2.5A, allowing it to deliver over 2A DC current to the load depending on the application conditions. The output voltage can be adjusted from 1.235V to 35V. The high current level is achieved thanks to an SO8 package with an exposed frame, which reduces the Rth(j-amb) to approximately 40°C/W. The device uses an internal P-Channel D-MOS transistor (with a typical Rdson of 250mΩ) as the switching element to minimize the size of external components. An internal oscillator sets the switching frequency at 250KHz. With a minimum input voltage of only 4.4V, it is particularly suitable for applications with a 5V bus available in computer-related applications. Pulse by pulse current limit
