Texas Instruments TPS65930BZCHR

Overview

TPS65930BZCHR from Texas Instruments is an integrated power management and audio codec IC for battery-powered portable devices including cellular phones and media players. It integrates three stepdown DC/DC converters, four external LDOs, a 16-bit stereo audio DAC/ADC, USB 2.0 OTG transceiver with ULPI interface, RTC, keypad controller, LED drivers, and SmartReflex™ dynamic voltage management.

For engineers reviewing the TPS65930BZCHR datasheet, TPS65930BZCHR pinout, TPS65930BZCHR application, or TPS65930BZCHR equivalent, this device supports OMAP2430/OMAP3430 host integration, offers configurable power modes (SLEEP/ACTIVE/OFF) via I²C, delivers 96 kHz RX path audio sampling, and provides dual LED drive (160 mA + 60 mA) in a 139-ball, 0.65 mm pitch, 10 × 10 mm BGA package.

Technical Context

The TPS65930BZCHR implements a multi-subchip architecture: Power subchip manages three SMPS and four LDOs with I²C-programmable output voltages and SLEEP/ACTIVE/OFF modes; Audio subchip includes I²S/TDM interface, PLL supporting 19.2/26/38.4 MHz clocks, 16-bit stereo DAC (96/48/44.1 kHz), and ADC with ALC and sidetone.

USB subchip integrates a 480 Mbps OTG-compliant transceiver with ULPI interface, 5V-tolerant data lines, and on-chip 480 MHz PLL; Auxiliary subchip contains two 10-bit MADC inputs, 6×6 keypad controller with debounce timer, and dual LED drivers (LEDA: 160 mA, LEDB: 60 mA); Interface subchip handles primary/secondary interrupts and 15 GPIOs via I²C and OCP bus.

Key Specifications

Pinout & Package

TPS65930BZCHR uses a 139-ball, 0.65 mm pitch, 10 mm × 10 mm BGA package (ball map per TI SWCS035A). Pinout is defined by functional ball assignment across power, audio, USB, interface, and auxiliary domains - no generic or inferred pin roles are used.

FAQ

What is the primary function of the TPS65930BZCHR in an OMAP-based system?

The TPS65930BZCHR serves as the central power management and audio subsystem for OMAP2430 and OMAP3430 processors. It delivers regulated voltages via three SMPS and four LDOs, provides 16-bit stereo audio conversion, hosts a USB 2.0 OTG transceiver with ULPI interface, and integrates RTC, keypad, LED, and MADC functions - all coordinated through a unified I²C control interface. Its SmartReflex support enables dynamic voltage scaling synchronized with OMAP processor states.

Does the TPS65930BZCHR support 96 kHz audio sampling on both DAC and ADC paths?

The TPS65930BZCHR supports 96 kHz sampling only on the DAC receive (RX) path when MCLK = 26 MHz; the ADC transmit (TX) path is limited to 48 kHz, 44.1 kHz, and 32 kHz sampling rates. This asymmetric capability is documented in the MODULE DESCRIPTION section of the SWCS035A datasheet and reflects hardware design constraints in the analog front-end and clock PLL configuration.

What are the key differences between the TPS65930BZCHR and the TPS65950?

The TPS65950 is a functional successor with an enhanced USB 2.0 PHY, additional GPIOs (15 → 22), improved thermal resistance (RθJA = 29.1°C/W), and support for OMAP36xx/OMAP4 processors - but it lacks CEA-936A carkit analog interface and is not pin-compatible with the TPS65930BZCHR. The TPS65930BZCHR remains the only option for legacy OMAP2430/OMAP3430 designs requiring carkit compliance and exact mechanical fit.

Can the TPS65930BZCHR operate in USB host mode without external components?

Yes - the TPS65930BZCHR includes a fully integrated USB 2.0 OTG-compliant transceiver with ULPI interface and on-chip 5 V charge pump for VBUS generation. When configured as host, it supplies regulated 5 V to downstream devices via VBUS and handles high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) signaling without external PHY or level shifters, meeting CEA-2011 and USB 2.0 specifications.

How does the SmartReflex feature work in the TPS65930BZCHR?

The SmartReflex feature in the TPS65930BZCHR dynamically adjusts output voltages of its SMPS regulators based on real-time processor activity and temperature feedback from OMAP2430/OMAP3430. It uses I²C communication to receive voltage requests from the host processor and implements closed-loop DVFS (Dynamic Voltage and Frequency Scaling) to minimize active power without compromising timing margins - validated for use with TI's OMAP SmartReflex-enabled silicon.
