SLVSBL2D – OCTOBER 2012 – REVISED JUNE 2017
TPD5S115 HDMI Companion Chip With Step-Up DC-DC Converter,
Level-Shifter, and ESD Clamp
1 Features
3 Description
•
The TPD5S115 device is an integrated HDMI
companion chip solution. The device provides a
regulated 5-V output (5VOUT) for sourcing the HDMI
power line. The regulated 5-V output supplies up to
55 mA to the HDMI receiver with a current limiting
function. The TPD5S115 features two control signals:
EN and LS_OE. The control of 5VOUT and the hot
plug detect (HPD) circuitry is independent of the
LS_OE control signal and is controlled by the EN pin.
The EN pin allows the detection scheme (5VOUT +
HPD) to be active before turning on the whole HDMI
link. The LS_OE activates the internal LDO, CEC,
SCL, and SDA buffers only when EN is also
activated. This dual stage enable scheme ensures
optimized power saving for portable applications.

There are three noninverting, bidirectional, voltage
level translation circuits for the SDA, SCL, and CEC
lines. Each have a common power rail (VCCA) on the
A side from 1.1 V to 3.6 V. On the B side, the SCL_B
and SDA_B each have an internal 1.75-kΩ pullup
connected to the regulated 5-V rail (5VOUT). The
DDC (SCL_B and SDA_B) pins meet the I2C
specification and drive up to 750-pF loads with the
buffers. The CEC_B pin has an internal 27-kΩ pullup
to an internal 3.3-V supply. The TPD5S115 exceeds
the IEC61000-4-2 (Level 4) ESD protection level. This
device features a space saving, 1.72-mm × 1.72-mm,
YFF package with 0.4-mm pitch.

7 Detailed Description
7.1 Overview
The TPD5S115 is an integrated interface solution that covers HDMI versions' 2.0, 1.4, and 1.3 need for power
supply voltage management and control line level translation. On the power supply line, it has a DC-DC
converter that takes the internal power supply from 2.3 V to 5.5 V, and outputs a regulated and current-limited,
5‑V voltage to the connector. The drivers support level translation on HPD, ECE, SCL, and SDA lines in both
transmission directions. Moreover, the rise-time acceleration feature helps drive the high capacitive load on the
cable side. Every channel comes with robust ESD protection with ±14-kV contact and ±16-kV air-gap
IEC61000‑4-2 capability.
7.2 Functional Block Diagram
(1)
3.3 V (internal) is an internal 3.3-V supply rail which is generated from 5VOUT when EN and LS_OE are HIGH.
(2)
LS_OE_INT is an internal control signal generated from EN and LS_OE signals. LS_OE_INT is active when both EN
and LS_OE are HIGH.
7.3 Feature Description
7.3.1 Rise-Time Accelerators
The HDMI cable side of the DDC lines incorporates rise-time accelerators to support the high capacitive load on
the HDMI cable side. The rise-time accelerator boosts the cable-side DDC signal, independent of which side of
the bus is releasing the signal.

Figure 12. Receiving and Transmitting Interaction
7.3.2 Hot Plug Detect
After the TPD5S115’s DC-DC converter and HPD block are enabled through the EN pin, the TPD5S115 is ready
for continual HDMI receiver detection. After a HDMI cable connects a receiving and transmitting device together,
the 5-V signal from the DC-DC output flows through the receiving device’s internal resistor and into HPD’s input.
The HPD buffer’s output then goes high, indicating to the transmitter that a receiving device is connected. To
save power, periodic detection can be done by turning on and off the DC-DC converter before a receiving device
is connected.
NOTE
Ground offset between the TPD5S115 ground and the ground of devices on port A of the
TPD5S115 must be avoided. A CMOS or NMOS open-drain capable of sinking 3 mA of
current at 0.4 V has an output resistance of 133 Ω or less (R = E / I). Such a driver shares
enough current with the port A output pulldown of the TPD5S115 to be detected as a LOW
while the ground offset is zero. If the ground offset is greater than 0 V, then the driver
resistance must be less. Because VILC can be as low as 90 mV at cold temperatures and
the low end of the current distribution, the maximum ground offset should not exceed 50
mV. Bus repeaters that use an output offset are not interoperable with the port A of the
TPD5S115 as their output LOW levels are not recognized by the TPD5S115 as a LOW. If
the TPD5S115 is placed in an application where the VIL of port A of the TPD5S115 does
not go below its VILC it will pull port B LOW initially when port A input transitions LOW but
the port B will return HIGH, so it does not reproduce the port A input on port B. Such
applications must be avoided. Port B is interoperable with all I2C-bus slaves, masters, and
repeaters.

Feature Description (continued)
7.3.3 CEC Level Shift Operation
The CEC level shift function operates in the same manner as the DDC lines except that the CEC line does not
need the rise time accelerator function.
7.3.4 Pullup Resistor
The system is designed to work properly with no external pullup resistors on the DDC, CEC, and HPD lines.
7.3.5 Undervoltage Lockout
The undervoltage-lockout circuit prevents the DC-DC converter from malfunctioning at low input voltages and
from excessive discharge of the battery. It disables the output stage of the converter once the falling VIN trips the
undervoltage-lockout threshold (VBATUV). The undervoltage-lockout threshold for falling VIN is typically 2 V. The
device starts operation once the rising VIN trips the under-voltage-lockout threshold again at 2.1 V (typical).
7.3.6 Soft Start
The DC-DC converter has an internal soft-start circuit that controls the ramp-up of the output voltage. The output
voltage reaches its nominal value within 250 µs (typical) after EN has been pulled high. The output voltage
ramps up from 5% to its nominal value within 300 µs (typical). This limits the in-rush current in the converter
during start-up and prevents possible input voltage drops when a battery or high impedance power source is
used. During soft start, the switch current limit is reduced to 300 mA until the output voltage reaches VIN. Once
the output voltage trips this threshold, the device operates with its nominal current limit.
7.4 Device Functional Modes
7.4.1 Power-Save Mode
The TPD5S115 integrates a power-save mode to improve efficiency at light loads. In power-save mode, the
converter only operates when the output voltage trips below a set threshold voltage. It ramps up the output
voltage with several pulses and goes into power-save mode once the output voltage exceeds the set threshold
voltage. The PFM mode is ended and PWM mode begins in case the output current can no longer be supported
in PFM mode.
7.4.2 Enable
The DC-DC converter is enabled when the EN is set to high. At first, the internal reference is activated and the
internal analog circuits are settled. Afterwards, the soft start is activated and the output voltage is ramped up.
The output voltage reaches its nominal value in 250 µs (typical) after the device has been enabled. The EN input
can be used to control power sequencing in a system with various DC-DC converters. The EN pin can be
connected to the output of another converter to drive the EN pin high and create a sequencing of supply rails.
When EN = GND, the converter enters shutdown mode.

8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The TPD5S115 is an integrated solution for HDMI 2.0, 1.3, and 1.4 interfaces. The device has a boost converter
on the power supply, signal conditioning circuits on CEC, SCL, SDA, and HPD lines, and ESD protection on all
the connector-facing lines.
8.2 Typical Applications
8.2.1 DDC or CEC Level Shifter
The TPD5S115 enables DDC translation from VCCA (system side) voltage levels to 5-V (HDMI cable side)
voltage levels without degradation of system performance. The TPD5S115 contains 2 bidirectional, open-drain
buffers specifically designed to support up and down-translation between the low voltage, VCCA side DDC-bus
and the 5-V DDC-bus. The port B I/Os are overvoltage tolerant to 5.5 V, even when the device is shutdown. After
power up and with the LS_OE and EN pins HIGH, a LOW level on port A (below VILC = 0.08 × VCCA) turns the
corresponding port B driver (either SDA or SCL) on and drives port B down to VOLB. When port A rises above
approximately 0.10 × VCCA, the port B pulldown driver is turned off and the internal pullup resistor pulls the pin
HIGH. When port B falls first and goes below 0.3 × VOUT, a CMOS hysteresis input buffer detects the falling
edge, turns on the port A driver, and pulls port A down to approximately VOLA = 0.16 × VCCA. The port B pulldown
is not enabled unless the port A voltage goes below VILC. If the port A low voltage goes below VILC, the port B
pulldown driver is enabled until port A rises above (VILC + ΔVT-HYSTA), then port B, if not externally driven LOW,
continues to rise being pulled up by the internal pullup resistor.

•
•
The threshold of CMP1 is approximately 150 mV ± the 40 mV of total hysteresis
The comparator trips for a falling waveform at approximately 130 mV
The comparator trips for a rising waveform at approximately 170 mV
To be recognized as a zero, the level at port A must first go below 130 mV (VILC in spec) and then stay below
170 mV (VILA in spec)
To be recognized as a one, the level at A must first go above 170 mV and then stay above 130 mV
VILC is specified as 110 mV in Electrical Characteristics to give some margin to the 130 mV
VILA is specified as 140 mV in Electrical Characteristics to give some margin to the 170 mV
VIHA is specified as 70% of VCCA to be consistent with standard CMOS levels
8.2.1.2.2 Input Capacitor
Due to the nature of the boost converter having a pulsating input current, a low-ESR input capacitor is required to
prevent large voltage transients that can cause poor performance of the device or interference with other circuits
in the system. TI recommends a 1.2-µF (minimum) input capacitor to improve transient behavior of the regulator
and EMI behavior of the total power-supply circuit. TI recommends placing a ceramic capacitor (4.7 µF) as close
as possible to the VIN and GND pins to improve the input noise filtering.
8.2.1.2.3 Output Capacitor
TI recommends using a small ceramic capacitors placed as close as possible to the VOUT and GND pins of the
IC. If the application requires the use of large capacitors which can not be placed close to the IC, TI recommends
using a smaller ceramic capacitor in parallel to the large capacitor. This small capacitor must be placed as close
as possible to the VOUT and GND pins of the IC. Use Equation 1 to estimate the recommended minimum output
capacitance.
Cmin =
IOUT ´ (VOUT - VIN )
f ´ DV ´ VOUT
where
•
•
f is the switching frequency
ΔV is the maximum allowed ripple
(1)
If a ripple voltage of 10 mV is chosen, a minimum effective capacitance of 2.7 µF is needed. The total ripple is
larger due to the ESR of the output capacitor. This additional component of the ripple can be calculated using
Equation 2.
DVESR = IOUT ´ RESR
(2)
To maintain control loop stability, a capacitor with a value in the range of the calculated minimum must be used.
There are no additional requirements regarding minimum ESR. There is no upper limit for the output capacitance
value. Larger capacitors cause lower output voltage ripple as well as lower output voltage drop during load
transients.

Ceramic capacitors have a DC-bias effect, which has a strong influence on the final effective capacitance
needed. Therefore the appropriate capacitor value must be chosen very carefully. Package size, voltage rating,
and material are responsible for differences between the rated capacitor value and the effective capacitance. The
minimum effective capacitance value is 1.2 µF, but the recommended value is 4.7 µF.

8.2.2 Other Application Circuits
Figure 15 and Figure 16 show application examples using the TPD5S115 devices. Customers must fully validate
and test any circuit before implementing a design based on an example in this section. Unless otherwise noted,
the design procedures in DDC or CEC Level Shifter are applicable.
Figure 15. Application Schematic for HDMI Controllers With One GPIO for HDMI Interface Control
Some HDMI controllers may have only one GPIO to control the HDMI interface, thus, the HDMI driver chip
controls the TPD5S115 through only one control line (EN). In this mode the HPD_A to LS_OE pins are
connected to each other (see Figure 15).

Some HDMI driver chips may have two GPIOs to control the HDMI interface chip. In this case a flexible power
saving mode can be implemented. The LS_OE and EN are active-high enable pins. They control the TPD5S115
power-saving options according to Table 3 and Table 4.

10 Layout
10.1 Layout Guidelines
For proper operation, follow these layout and design guidelines:
• Place the TPD5S115 as close to the connector as possible. This allows it to remove the energy associated
with ESD strike before it reaches the internal circuitry of the system board.
• Place power line capacitors and inductors close to the pins with wide traces to allow enough current to flow
through with less trace parasitics. Ensure that there is enough metallization for the GND pad. A sufficient
current path enables safe discharge of all the energy associated with the ESD strike.
