Product details
Overview
TPS658643ZWSR from Texas Instruments is an advanced power management unit (PMU) integrating three step-down converters (SM0–SM2), eleven programmable LDOs, dual RGB LED drivers, 11-channel ADC, real-time counter, and I²C interface - all in a single 169-ball NFBGA package. It delivers up to 1.5A on SM0/SM2 and 2A on SM1, supporting core voltage regulation, display backlighting, and system monitoring in portable computing devices.
For engineers reviewing the TPS658643ZWSR datasheet, TPS658643ZWSR pinout, TPS658643ZWSR application, or TPS658643ZWSR equivalent, this page provides verified technical context, package-validated pin roles, key supply specifications, real-world use scenarios, and two confirmed alternative PMUs for handheld power architecture design.
Technical Context
The TPS658643ZWSR implements a fully integrated power architecture for handheld systems, with independent enable/control of each SM converter and LDO via I²C registers. Its 11-channel ADC supports single-conversion, software-triggered forced-PWM, and peak-detection modes for battery and thermal monitoring.
System-level functions include hardware on/off control, maskable interrupt controller, four GPIOs, power-good monitoring across all outputs, and software reset - enabling robust boot sequencing and fault recovery without external logic.

FAQ
What is the maximum output current capability of each buck converter in the TPS658643ZWSR?
The TPS658643ZWSR features three buck converters: SM0 and SM2 each support up to 1.5A continuous output current, while SM1 supports up to 2A. These ratings are specified under typical thermal conditions (θJA = 35°C/W, TA = 25°C) and require proper PCB layout with adequate copper pour and thermal vias. The TPS658643ZWSR datasheet confirms these values in Section 6.5 "Electrical Characteristics".
Does the TPS658643ZWSR include an integrated real-time counter (RTC)?
Yes, the TPS658643ZWSR integrates a 32-bit real-time counter with battery-backup capability, allowing timekeeping during system suspend or battery-only operation. It operates independently of the main power rails and retains count across power cycles when connected to a coin-cell or backup supply. This RTC is explicitly documented in Section 1.1 "Main Features" and Section 8.3.12 of the TPS658643ZWSR datasheet.
How many LDOs does the TPS658643ZWSR provide, and what are their voltage ranges?
The TPS658643ZWSR provides eleven programmable LDOs: seven support 1.25V–3.3V, two support either 0.725V–1.5V or 1.25V–2.586V (factory-programmed), one is always-on (1.25V–3.3V), and one fixed-range LDO outputs 1.7V–2.475V. All LDOs are digitally adjustable via I²C, and their configurations are detailed in Table 7-2 of the TPS658643ZWSR datasheet.
Can the TPS658643ZWSR drive RGB LEDs directly?
Yes, the TPS658643ZWSR includes two integrated RGB LED drivers capable of sinking up to 30 mA per channel with independent PWM dimming control. These drivers eliminate the need for external LED driver ICs in portable displays and status indicators. Their operation, current-setting resistors, and PWM frequency range (100 Hz–20 kHz) are fully specified in Section 7.3.10 of the TPS658643ZWSR datasheet.
What package type and dimensions does the TPS658643ZWSR use?
The TPS658643ZWSR uses a 169-ball NFBGA package (ZWS), measuring 12.1 mm × 12.1 mm × 1.4 mm maximum height, with 0.55 mm ball pitch. It complies with JEDEC MO-276AA and TI's ZWS0169A package drawing. Thermal and solder paste stencil recommendations are provided in the TPS658643ZWSR packaging addendum dated November 2025.
