2 / 19 page UC28023 UC28025 SLUS557F -- MARCH 2003 -- REVISED AUGUST 2010 2 www.ti.com 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. ABSOLUTE MAXIMUM RATINGS over operating free-air temperature range unless otherwise noted(1) UC28023 UC28025 RATING UNIT Input voltage range, VC, VCC VC, VCC 30 V Output current, IOUT(DC) OUT OUTA, OUTB ±0.5 A Peak output current, pulsed 0.5 ms IOUT(pulsed) OUT OUTA, OUTB ±2.0 A Capacitive load, CLOAD 200 pF INV, NI, RAMP INV, NI, RAM --0.3Vto7V Analog inputs SS, ILIM/SD SS, ILIM/SD VREF +0.3 V, --0.3 V V Output current, IREF VREF VREF 10 Output current, ICLOCK CLOCK CLOCK --5 Soft-start sink current, ISINK_SS SS SS 5 mA Output current, IOUT(EA) EAOUT EAOUT 20 mA Oscillator charging current, IOSC_CHG RT RT --5 Power Dissipation at TA =25°C (all packages) 1 W Operating junction temperature range, TJ --55 to 150 Storage temperature, Tstg --65 to 150 °C Lead temperature 1,6 mm (1/16 inch) from case for 10 seconds, Tsol 300 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. All voltages are with respect to GND. All currents are positive into and negative out of the specified terminal. |
