Texas Instruments TPS65930BZCH

Overview

TPS65930BZCH from Texas Instruments is an integrated power management and audio codec IC for battery-powered portable devices, featuring three configurable step-down DC/DC converters (up to 1.5 A), four external LDOs, a 16-bit stereo audio DAC (96 kHz support), 16-bit stereo ADC, USB 2.0 OTG-compliant transceiver with ULPI interface, and SmartReflex™ dynamic voltage management. It serves as the central PMIC/audio hub in OMAP-based smartphones and media players.

For engineers reviewing the TPS65930BZCH datasheet, TPS65930BZCH pinout, TPS65930BZCH application, or TPS65930BZCH equivalent, key selection considerations include its 139-ball 0.65 mm pitch BGA package, I²C programmable power states (SLEEP/ACTIVE/OFF), dual-path audio sampling (48 kHz TX/RX, 96 kHz RX-only), integrated LED drivers (160 mA/60 mA), and RTC with retention capability.

Technical Context

The TPS65930BZCH integrates five functional subchips-Power (SMPS + LDOs), Audio (I²S/TDM, PLL, DAC/ADC), USB (ULPI PHY, 5V-tolerant VBUS, 480 MHz PLL), Auxiliary (MADC, keypad, LED), and Interface (dual interrupt handlers, 15 GPIOs, OCP bus)-all coordinated via a centralized I²C control interface and internal Open Core Protocol interconnect.

Its audio PLL supports 19.2 MHz, 26 MHz, and 38.4 MHz reference clocks and enables simultaneous dual-port operation or single TDM port use; the USB subchip implements full-speed (12 Mbps) and high-speed (480 Mbps) modes with CEA-2011/CEA-936A carkit compliance and integrated 5 V charge pump for VBUS supply.

Key Specifications

Pinout & Package

FAQ

What is the primary function of the TPS65930BZCH in a portable system?

The TPS65930BZCH serves as an integrated power management and audio codec IC, combining three step-down DC/DC converters, four LDOs, a 16-bit stereo DAC/ADC, USB 2.0 OTG transceiver, and SmartReflex™ dynamic voltage management. In systems like OMAP-based smartphones, the TPS65930BZCH consolidates power regulation, audio processing, USB connectivity, and peripheral control into a single 139-ball BGA package - reducing bill-of-materials count and PCB complexity while enabling coordinated power and audio timing.

Does the TPS65930BZCH support 96 kHz audio sampling, and if so, on which path?

Yes, the TPS65930BZCH supports 96 kHz sampling exclusively on the receive (RX) path of the audio subsystem when using a 26 MHz master clock (MCLK), as confirmed in the SWCS035A datasheet. The transmit (TX) path supports up to 48 kHz. This asymmetric capability allows high-resolution playback while maintaining lower-power voice capture - a design choice aligned with its target use in mobile handsets where RX fidelity is prioritized for media consumption.

Is the TPS65930BZCH pin-compatible with the TPS65950 or TPS65910?

No, the TPS65930BZCH is not pin-compatible with either the TPS65950 (139-ball vs. 168-ball package) or the TPS65910 (139-ball vs. 107-ball package). The TPS65950 introduces additional USB and HDMI-related signals, while the TPS65910 removes USB PHY pins and reduces LDO and GPIO count. Board-level replacement requires full schematic and layout revision; the TPS65930BZCH must be sourced as a standalone solution for OMAP2/3 designs.

What USB standards and interface modes does the TPS65930BZCH support?

The TPS65930BZCH supports USB 2.0 OTG compliance with high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) operation. It implements the ULPI (UTMI+ Low Pin Interface) standard for connection to a USB link controller and includes a 5 V-tolerant data line and VBUS tolerance up to 6 V. Its integrated 480 MHz PLL derives timing from the internal system clock, eliminating need for external crystal or oscillator in USB applications.

How does the SmartReflex™ feature operate within the TPS65930BZCH?

SmartReflex™ in the TPS65930BZCH provides hardware-coordinated dynamic voltage and frequency scaling (DVFS) by receiving activity signals from compatible OMAP processors (e.g., OMAP2430/3430) and adjusting SMPS output voltages in real time. This reduces active power consumption during low-workload states without software intervention - a key enabler for extended battery life in smartphones where CPU voltage can be scaled below nominal levels while maintaining system stability.
