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. NOTE 1: All voltage values are with respect to network ground terminal. DISSIPATION RATING TABLE PACKAGE TA ≤ 25°C POWER RATING DERATING FACTOR ABOVE TA = 25°C TA = 70°C POWER RATING TA = 85°C POWER RATING 10 pin MSOP 555 mW 5.56 mW/ °C 305 mW 221 mW 12 pin YEG 588 mW 5.87 mW/ °C 324 mW 235mW NOTE: The thermal resistance junction to ambient of the 10-pin MSOP is 180 °C/W. The thermal resistance junction to ambient of the 12-pin YEG is 170 °C/W and RθJC = 21°C/W. The device will not run into thermal limitations provided it is operated within the specified range. recommended operating conditions MIN TYP MAX UNIT Supply voltage, VI 2 5.5 V Output voltage range for adjustable output voltage version, VO 0.8 VI V Output current for 3-cell operation, IO (VI ≥ 2.5 V; L = 10 µH, f = 750 kHz) 600 mA Output current for 2-cell operation, IO (VI ≥ 2 V; L = 10 µH, f = 750 kHz) 200 mA Inductor, L (see Note 2) 10 µH Input capacitor, Ci (see Note 2) 10 µF Output capacitor, Co (see Note 2) VO ≥ 1.8 V) 10 µF Output capacitor, Co (see Note 2) VO < 1.8 V) 47 µF Operating ambient temperature, TA -40 85 °C Operating junction temperature, TJ -40 125 °C NOTE 2: Refer to application section for further information. |
