Integrated Power Management
\Audio Codec (TPS65930 Only)
Check for Samples: TPS65930/TPS65920

Introduction
The TPS65920/TPS65930 devices are power-management ICs for OMAP
and other mobile
applications. The devices include power-management, a universal serial bus (USB) high-speed (HS)
transceiver, light -emitting diode (LED) drivers, an analog-to-digital converter (ADC), a real-time clock
(RTC), and embedded power control (EPC). In addition, the TPS65930 includes a full audio codec with
two digital-to-analog converters (DACs) and two ADCs to implement dual voice channels, and a stereo
downlink channel that can play all standard audio sample rates through a multiple format inter-integrated
sound (I2S
)/time division multiplexing (TDM) interface.
These optimized devices support the power and peripheral requirements of the OMAP application
processors. The power portion of the devices contains three buck converters, two controllable by a
dedicated SmartReflex
class-3 interface, multiple low dropout (LDO) regulators, an EPC to manage the
power sequencing requirements of OMAP, and an RTC and backup module. The RTC can be powered by
a backup battery when the main supply is not present, and the devices include a coin-cell charger to
recharge the backup battery as needed.
The USB module provides a HS 2.0 OTG transceiver suitable for direct connection to the OMAP UTMI+
low pin interface (ULPI), with an integrated charge pump and full support for the carkit CEA-936A
specification. An ADC is provided for monitoring signals, such as supply voltage, entering the device, and
two additional external ADC inputs are provided for system use.
The devices provide driver circuitry to power two LED circuits that can illuminate a panel or provide user
indicators. The drivers also provide pulse width modulation (PWM) circuits to control the illumination levels
of the LEDs. A keypad interface implements a built-in scanning algorithm to decode hardware-based key
presses and reduce software use, with multiple additional general-purpose input/output devices (GPIOs)
that can be used as interrupts when configured as inputs.
This TPS65920/TPS65930 data manual presents the electrical and mechanical specifications for the
TPS65920 and TPS65930 devices
. It covers the following topics:
TPS65920/TPS65930 terminals: Assignment, multiplexing, electrical characteristics, and functional
description (see Section 2, Terminal Description)
Electrical characteristic requirements: Maximum and recommended operating conditions, digital
input/output (I/O) characteristics (see Section 3, Electrical Characteristics)
Power module: Power provider, power references, power control, power consumption, and power
management, with the on and off sequence (see Section 4, Power Module)
RTC and EPC (see Section 5, Real-Time Clock and Embedded Power Controller)
Audio/voice module (TPS65930 device only): Electrical characteristics and application schematics for
the downlink and uplink paths (see Section 6, Audio/Voice Module (TPS65930 Device Only))
Various modules: USB transceiver, monitoring analog-to-digital converter (MADC), LED drivers, and
keyboard (see Section 8, MADC, Section 9, LED Driver, and Section 10, Keyboard)
Clock specifications: Clock slicer; input and output clocks (see Section 11, Clock Specifications)
Timing requirements and switching characteristics (ac timings) of the interfaces (see Section 12,
Timing Requirements and Switching Characteristics)
