Product Overview
The TPS61032 is a Texas Instruments synchronous boost converter in the Power_Management category. For the TPS61032 variant, the output voltage option is 5 V fixed, with a recommended VBAT supply range of 1.8 to 5.5 V and an operating ambient temperature range of -40 to 85 °C. The recommended virtual junction temperature range is -40 to 125 °C.
The converter operates with a 600 kHz typical oscillator frequency and supports external synchronization from 500 to 700 kHz. Its DC/DC stage specifies 55 mΩ typical SWN and SWP switch on resistance, -3% to 3% total accuracy, 0.6% line regulation, and 0.6% load regulation. The switch current limit is 3600 mA minimum, 4000 mA typical, and 4500 mA maximum at VOUT = 5 V.
Package options include a 16-pin TSSOP PowerPAD (PWP) and a 16-pin QFN (RSA). Thermal resistance values are specified for both packages, including junction-to-ambient, junction-to-case, junction-to-board, and junction-to-case-bottom paths. Applications should align with 5 V boost rails, low standby current requirements, low-battery indication, synchronization, and thermal design limits from the datasheet.
