PRODUCTION DATA. TPS53632G 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 1 Features 1 • Valley Current Mode with Constant ON Time Control • Lossless Current Sensing Scheme • I2C Interface for VID Control and Telemetry • Programmable I2C Addresses up to Eight Devices • Switching Frequency up to 1 MHz • Digital Current Monitor • 7-Bit, DAC Output Range: 0.50-V to 1.52-V with 10-mV Step • Accurate, Adjustable Voltage Positioning or Zero Slope Load-Line • Selectable, 8-Level Current Limit • Adjustable Output Slew Rate Control • Default Boot Voltage: 1.00 V • Small, 4-mm × 4-mm, 32-Pin, VQFN, PowerPAD Package 2 Applications • 48-V Point-of-Load (POL) for Data Center and Telecommunication • Wide Input Range Power Supplies for Industrial 3 Description The TPS53632G device is a half-bridge PWM controller with D-CAP+™ 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. Other features include adjustable control of output slew rate and voltage positioning. In addition, the TPS53632G device can be used along with other TI discrete power MOSFETs and drivers for 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 and 105°C.
