TPS43336QDAPRQ1 TI Power Management IC | 38-HTSSOP | Dual 3A Buck Controller

Product Overview

The TPS43336QDAPRQ1 from Texas Instruments is a dual-channel synchronous buck controller designed for automotive and industrial applications. It operates over a wide input voltage range of 4.5V to 40V, making it suitable for 12V and 24V battery systems. Each channel can deliver up to 3A continuous output current with excellent line and load regulation. The device integrates high-side and low-side MOSFET drivers, reducing external component count and simplifying PCB layout. With its 38-HTSSOP package, it offers a compact solution for space-constrained designs.
