2 / 43 page UCC28070A SLUSAW0 – MARCH 2012 www.ti.com DESCRIPTION (CONT.) Like UCC28070, UCC28070A also features multiple innovations including current synthesis and quantized voltage feed-forward to promote performance enhancements in PF, efficiency, THD, and transient response. Features including frequency dithering, clock synchronization, and slew rate enhancement further expand the potential performance enhancements. All protection features in UCC28070 such as output over-voltage detection, programmable peak-current limit, under-voltage lockout and open-loop protection are available in UCC28070A as well. ORDERING INFORMATION PART NUMBER PACKAGE PACKING UCC28070APW Plastic, 20-Pin TSSOP (PW) 70-Pc. Tube UCC28070APWR Plastic, 20-Pin TSSOP (PW) 2000-Pc. Tape and Reel ABSOLUTE MAXIMUM RATINGS (1) (2) (3) (4) over operating free-air temperature range (unless otherwise noted) PARAMETER LIMIT UNIT Supply voltage: VCC 22 V Supply current: IVCC 20 mA Voltage: GDA, GDB −0.5 to VCC+0.3 V Gate drive current – continuous: GDA, GDB +/ − 0.25 A Gate drive current – pulsed: GDA, GDB +/ − 0.75 Voltage: DMAX, RDM, RT, CDR, VINAC, VSENSE, SS, VAO, IMO, CSA, CSB, −0.5 to +7 V CAOA, CAOB, PKLMT, VREF Current: RT, DMAX, RDM, RSYNTH −0.5 mA Current: VREF, VAO, CAOA, CAOB, IMO 10 Operating junction temperature, TJ −40 to +125 Storage temperature, TSTG −65 to +150 °C Lead temperature (10 seconds) 260 (1) These are stress limits. Stress beyond these limits may cause permanent damage to the device. Functional operation of the device at these or any conditions beyond those indicated under RECOMMENDED OPERATING CONDITIONS is not implied. Exposure to absolute maximum rated conditions for extended periods of time may affect device reliability. (2) All voltages are with respect to GND. (3) All currents are positive into the terminal, negative out of the terminal. (4) In normal use, terminals GDA and GDB are connected to an external gate driver and are internally limited in output current. 2 Submit Documentation Feedback Copyright © 2012, Texas Instruments Incorporated Product Folder Link(s): UCC28070A |
