DESCRIPTION/ORDERING INFORMATION
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.
