5 / 74 page  UCC28950 www.ti.com SLUSA16C – MARCH 2010 – REVISED NOVEMBER 2015 6 Specifications 6.1 Absolute Maximum Ratings over operating free-air temperature range (unless otherwise noted) (1) (2) MIN MAX UNIT Input supply voltage, VDD (3) –0.4 20 V OUTA, OUTB, OUTC, OUTD, OUTE, OUTF –0.4 VDD + 0.4 V Input voltage on DELAB, DELCD, DELEF, SS/EN, DCM, TMIN, RT, SYNC, RSUM, EA+, EA-, –0.4 VREF + 0.4 V COMP, CS, ADEL, ADELEF Output voltage on VREF –0.4 5.6 V Continuous total power dissipation See Dissipation Ratings Operating virtual junction temperature, TJ –40 +150 °C Operating ambient temperature, TA –40 +125 °C Lead temperature (soldering, 10 sec.) +300 °C Storage temperature, Tstg –65 +150 °C (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) These devices are sensitive to electrostatic discharge; follow proper device handling procedures. (3) All voltages are with respect to GND unless otherwise noted. Currents are positive into, negative out of the specified terminal. See Packaging Section of the datasheet for thermal limitations and considerations of packages. 6.2 ESD Ratings VALUE UNIT Human body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) 2000 V V(ESD) Electrostatic discharge Charged device model (CDM), per JEDEC specification JESD22- 500 V C101(2) (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. (2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. 6.3 Recommended Operating Conditions over operating free-air temperature range (unless otherwise noted) MIN NOM MAX UNIT Supply voltage range, VDD 8 12 17 V Operating junction temperature range –40 125 °C Converter switching frequency setting range, FSW(nom) 50 1000 kHz Programmable delay range between OUTA, OUTB and OUTC, OUTD set by 30 1000 ns resistors DELAB and DELCD and parameter KA (1) Programmable delay range between OUTA, OUTF and OUTB, OUTE set by 30 1400 ns resistor DELEF, and parameter KEF (1) Programmable DCM range as percentage of voltage at CS(1) 5% 30% Programmable TMIN range 100 800 ns (1) Verified during characterization only.
