The TPS53632GRSMT from Texas Instruments is a D-CAP+ architecture half-bridge PWM controller optimized for GaN-based 48-V DC/DC converters. It offers fast transient response, minimal output capacitance, and high efficiency in single-stage conversion directly from a 48-V bus.
This controller supports the I²C Rev 3.0 interface for dynamic output voltage control and current monitoring telemetry. It can switch up to 1 MHz when paired with TI GaN power stages and drivers, enabling smaller magnetic components and reduced board space. The device operates within an input voltage range of 3.1V to 28V and has an operating temperature range of -10°C to 105°C.
The TPS53632GRSMT is available in a compact 32-VQFN (4x4 mm) package and is suitable for surface mount applications. Key features include Valley Current Mode with Constant ON Time Control, a lossless current sensing scheme, and programmable I²C addresses for up to eight devices. It also includes digital current monitoring and adjustable output slew rate control.
