This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
DESCRIPTION (CONTINUED)
Compared to the TPS65160 and TPS65160A the TPS65161/A/B family of devices offer increased step-down
converter output current. The TPS65161B also offers increased charge pump output current, and a higher
undervoltage lockout threshold. The devices can be powered from a 12-V input supply and generate the four
main supply voltages required by TFT LCD display panels.
Each device comprises a boost converter to generate the source voltage VS, a step-down converter to generate
the logic supply V(LOGIC), and regulated positive and negative charge pumps to generate the TFT bias voltages
VGH and VGL. Both switching converters and both charge pumps operate from a central clock that can be set to
either 750-kHz or 500-kHz by tying the FREQ pin high or low.
The TPS65161/A/B devices feature adjustable power supply sequencing, plus a number of safety features such
as boost converter overvoltage protection, buck converter short-circuit protection, and thermal shutdown. The
devices also incorporate a gate drive signal to control an external MOSFET isolation switch connected in series
with VS or VGH (see the application section at the end of this data sheet for more information).

For the most current package and ordering information, see the Package Option Addendum at the end of this document, or see the TI
Web site at www.ti.com.
(2)
Because of the charge pumps' 50% duty cycle, the maximum current available from VGH and VGL in typical applications is equal to
approximately half the charge pump current limit.
(3)
The PWP package is available taped and reeled. Add R-suffix to the device type (TPS65161PWPR) to order the device taped and
reeled. The TPS65161PWPR package has quantities of 2000 devices per reel. Without suffix, the TPS65161PWP is shipped in tubes
with 50 devices per tube.

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating
conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
