(2) For customized output voltage range, default output voltage and I2C address, contact the factory. (3) The YZG package is available in tape and reel. Add R suffix (TPS6235xYZGR, TPS6235xDRCR) to order quantities of 3000 parts. Add T suffix (TPS6235xYZGT, TPS6235xDRCT) to order quantities of 250 parts. 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. (4) The following registers bits are set by internal hardware logic and not user programmable through I2C: a. VSEL0[7:6] = 11 b. VSEL1[7:6] = 11 c. CONTROL1[4:2] = 100 d. CONTROL2[7:6] = 10, CONTROL2[4:3] = 00 over operating free-air temperature range (unless otherwise noted) (1) UNITS Voltage at AVIN, PVIN(2) -0.3 V to 7 V Voltage at SW (2) -0.3 V to 7 V VI Voltage at EN, VSEL, SCL, SDA, SYNC (2) -0.3 V to 7 V Voltage at FB(2) -0.3 V to 4.2 V Power dissipation Internally limited TJ Maximum operating junction temperature 150 °C Tstg Storage temperature range –65 °C to 150°C Human body model 2 kV ESD rating(3) Charge device model 1 kV Machine model 200 V (1) 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. (2) All voltage values are with respect to network ground terminal. (3) The human body model is a 100-pF capacitor discharged through a 1.5-k Ω resistor into each pin. The machine model is a 200-pF capacitor discharged directly into each pin. 2 Submit Documentation Feedback Copyright © 2006–2008, Texas Instruments Incorporated Product Folder Link(s): TPS62350, TPS62351 TPS62352, TPS62353 TPS62354, TPS62355, TPS62356 |
