Product Overview
The TPS62933 is a Texas Instruments synchronous buck converter categorized under Power_Management. It integrates high-side and low-side MOSFETs with 76 mohm and 32 mohm on resistance, respectively, and supports 3 A continuous output current for TPS62933 and TPS62933x variants. The recommended input voltage range is 3.8 V to 30 V, while the output voltage range is 0.8 V to 22 V.
Control is based on fixed-frequency peak current mode with internal loop compensation. The RT pin selects switching frequency from 200 kHz to 2.2 MHz, with 500 kHz when RT is floating and 1.2 MHz when RT is tied to GND. TPS62933 uses pulse frequency modulation for light-load operation.
The device is supplied in an 8-pin SOT583 DRL package with a 1.60 mm x 2.10 mm nominal body. Assembly-related limits include a 100 nF ceramic bootstrap capacitor from BST to SW and a minimum 6.8 nF SS capacitor, which sets the minimum soft-start time to approximately 1 ms.
