The TPS65232 provides one PWM buck controller, two adjustable, synchronous buck regulators. The SMPS have 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 stabilizing the system with minimum external components.
