SLUSCJ3A – APRIL 2016 – REVISED JUNE 2016 TPS53632G D-CAP+™ Half-Bridge PWM Controller
Optimized for GaN-based 48-V DC/DC Converter with I2C Interface
1 Features 3 Description The TPS53632G device is a half-bridge PWM
controller with D-CAP+в„ў architecture that provides
fast transient response, lowest output capacitance
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 control of
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 board
space. The LMG5200 GaN power stage is designed
specifically for this controller to achieve high
frequency and efficiency as high as 92% with 48-V to
1-V conversion. 1 Valley Current Mode with Constant ON Time
