4 / 45 page 4 TPS745-Q1 SBVS355A – JUNE 2019 – REVISED OCTOBER 2019 www.ti.com Product Folder Links: TPS745-Q1 Submit Documentation Feedback Copyright © 2019, Texas Instruments Incorporated Pin Functions (continued) PIN I/O DESCRIPTION NAME DRV (Fixed) DRV (Adjust) DRB (Fixed) DRB (Adjust) Thermal Pad — The thermal pad is electrically connected to the GND node. Connect to the GND plane for improved thermal performance. (1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) The absolute maximum rating is VIN + 0.3 V or 6.0 V, whichever is smaller. 6 Specifications 6.1 Absolute Maximum Ratings over operating free-air temperature range (unless otherwise noted) (1) MIN MAX UNIT Voltage Supply, VIN –0.3 6.5 V Enable, VEN –0.3 6.5 Feedback, VFB –0.3 2.0 Power-good, VPG –0.3 6.5 Output, VOUT –0.3 VIN + 0.3 (2) Current Output, IOUT Internally limited Power-good, IPG ±10 mA Temperature Operating junction, TJ –40 150 °C Storage, Tstg –65 150 (1) AEC Q100-002 indicates that HBM stressing shall be in accordance with the ANSI/ESDA/JEDEC JS-001 specification. 6.2 ESD Ratings VALUE UNIT V(ESD) Electrostatic discharge Human-body model (HBM), per AEC Q100-002(1) ±2000 V Charged-device model (CDM), per AEC Q100-011, corner pins ±750 Charged-device model (CDM), per AEC Q100-011, other pins ±500 (1) Minimum derated capacitance of 0.47 µF is required for stability. 6.3 Recommended Operating Conditions over operating free-air temperature range (unless otherwise noted) MIN NOM MAX UNIT VIN Input voltage 1.5 6.0 V VOUT Output voltage Adjustable only 0.55 5.5 V Fixed only 0.65 5.0 IOUT Output current 0 500 mA CIN Input capacitor 1 μF COUT Output capacitor(1) 1 220 μF CFF Feed-forward capacitor 10 nF VEN Enable voltage 0 6.0 V fEN Enable toggle frequency 10 kHz VPG PG voltage 0 6.0 V TJ Junction operating temperature –40 150 °C |
