TPS65232A0RHAR Description

The TPS65232A0RHAR provides one PWM buck controller, and two adjustable, synchronous buck regulators. The SMPS has integrated switching FETs for optimized power efficiency and reduced external component count. All power blocks have thermal and over-current/short-circuit protection. The TPS65232 startup timing can be controlled through buck enable pins. The buck controller and buck converters have internal pole/zero pairs to help stabilize the system with minimum external components.
