Texas Instruments TPS54353 4.5V to 20V Input, 1.5V Output, 3A Synchronous Step-Down SWIFT? Converter with Low-Side Gate Driver TPS54353PWP

The TPS54353PWP is a synchronous buck PWM converter designed for medium output current applications, featuring a fixed output voltage of 1.5V and a continuous output current capability of 3A. It incorporates a 100 m,Ѷ, 4.5-A peak MOSFET switch, ensuring high efficiency for various low power systems. The device supports external low-side MOSFET or diode configurations and is internally compensated to minimize component count. Key features include a wide PWM frequency range, adjustable from 250 kHz to 700 kHz, and synchronization capabilities with an external clock, allowing for 180¬8 out of phase operation. The TPS54353PWP also includes protection mechanisms such as peak current limit, thermal shutdown, and adjustable undervoltage lockout, enhancing reliability in demanding applications. This regulator is housed in a 16-pin TSSOP PowerPAD package, making it suitable for applications in industrial and commercial sectors, including LCD monitors, computer peripherals, and point of load regulation for high-performance DSPs, FPGAs, ASICs, and microprocessors.
