The TPS53632G device is a half-bridge PWM controller with D-CAP+ architecture
that provides fast transient response, lowest outputcapacitance and high
efficiency in single stage conversion directly from 48-V bus. The TPS53632G
device supports the standard I2C Rev 3.0 interface for dynamic
controlof the output voltage and current monitor telemetry. Paired with TI GaN
power stages and drivers,the TPS53632G can switch up to 1 MHz to minimize
magnetic component size and reduce overall boardspace. The LMG5200 GaN power
stage is designed specifically for this controller to achieve highfrequency
and efficiency as high as 92% with 48-V to 1-V conversion.
Other features include adjustable control of output slew rate and voltage
positioning. Inaddition, the TPS53632G device can be used along with other TI
discrete power MOSFETs and driversfor silicon-based half bridge solutions. The
TPS53632G device is packaged in a space saving,thermally enhanced, 32-pin VQFN
package and is rated to operate at a range between –10°C and105°C.
