11 Device and Documentation Support

11.1 Device Support

11.1.1 Development Support

11.1.1.1 Evaluation Modules

An evaluation module (EVM) is available to assist in the initial circuit performance evaluation using the TPS780. The TPS780XXEVM-301 evaluation module (and related user's guide) can be requested at the Texas Instruments website through the product folders or purchased directly from the TI eStore.

11.1.1.2 Spice Models

Computer simulation of circuit performance using SPICE is often useful when analyzing the performance of analog circuits and systems. A SPICE model for the TPS780 series is available through the product folders under Tools & Software.

11.1.2 Device Nomenclature

Table 8. Device Nomenclature(1)(2)

PRODUCT VOUT
TPS780vvvxxxyyyz vvv is the nominal output voltage for VOUT(HI) and corresponds to VSET pin low.
xxx is the nominal output voltage for VOUT(LO) and corresponds to VSET pin high.
yyy is the package designator.
z is the tape and reel quantity (R = 3000, T = 250).
Adjustable version(3)(4)
(1) For the most current package and ordering information see the Package Option Addendum at the end of this document, or see the TI website at www.ti.com.
(2) Additional output voltage combinations are available on a quick-turn basis using innovative, factory EPROM programming. Minimum order quantities apply; contact your sales representative for details and availability.
(3) To order the adjustable version, use TPS78001YYYZ.
(4) The device is either fixed voltage, dual-level VOUT, or adjustable voltage only. Device design does not permit a fixed and adjustable output simultaneously.

11.3 Trademarks

MSP430 is a trademark of TI.

All other trademarks are the property of their respective owners.

11.4 Electrostatic Discharge Caution

esds-image

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
