The TPS4002x utilizes a proprietary Predictive Gate Drive technology to minimize the diode conduction losses associated with the high-side and synchronous rectifier N-channel MOSFET transistions. The integrated charge pump with boost circuit provides a regulated 5-V gate drive for both the high side and synchronous rectifier N-channel MOSFETs. The use of the Predictive Gate Drive technology and charge pump/boost circuits combine to provide a highly efficient, smaller and less expensive converter. Design flexibility is provided through user programmability of such functions as: operating frequency, short circuit current detection thresholds, soft-start ramp time, and external synchronization frequency. The operating frequency is programmable using a single resistor over a frequency range of 100 kHz to 1 MHz. Higher operating frequencies yield smaller component values for a given converter power level as well as faster loop closure. 5 13 12 16 15 1 2 3 ILIM/ SYNC VDD OSNS COMP HDRV BOOT2 PVDD LDRV VDD 2.25 V − 5.5 V 4 FB 11 BOOT1 TPS40020 6 SS/SD 7RT 8 SGND VOUT 14 SW PGND 10 PWRGD 9 VDD VOUT UDG−02094 PRODUCTION DATA information is current as of publication date.
