NMOS Switch Leakage INLK — 0.15 — µA VIN = VSW = 5V VOUT = 5.5V VEN = VFB = GND PMOS Switch Leakage IPLK — 0.15 — µA VIN = VSW = GND; VOUT = 5.5V NMOS Switch ON Resistance RDS(ON)N — 0.45 — VIN = 3.3V, ISW = 100 mA PMOS Switch ON Resistance RDS(ON)P — 0.9 — VIN = 3.3V, ISW = 100 mA NMOS Peak Switch Current Limit IN(MAX) — 650 — mA Note 5 VOUT Accuracy VOUT% -3 — +3 % Includes Line and Load Regulation; VIN = 1.5V Line Regulation (V OUT/VOUT) / V IN -0.4 0.3 0.4 %/V VIN = 1.5V to 2.8V IOUT = 50 mA Load Regulation V OUT/VOUT -1.5 0.1 1.5 % IOUT = 25 mA to 100 mA; VIN = 1.5V Maximum Duty Cycle DCMAX 87 89 91 % Note 5 Switching Frequency fSW 425 500 575 kHz EN Input Logic High VIH 70 — — %of VIN IOUT = 1 mA EN Input Logic Low VIL — — 20 %of VIN IOUT = 1 mA EN Input Leakage Current IENLK — 5.0 — nA VEN = 5V Soft Start Time tSS — — 1.5 ms EN Low to High, 90% of VOUT; Note 4, Note 5 Thermal Shutdown Die Temperature TSD — 160 — C IOUT = 20 mA, VIN > 1.4V Die Temperature Hysteresis TSDHYS — 20 — C DC CHARACTERISTICS (CONTINUED) Electrical Characteristics: Unless otherwise indicated, VIN = 1.5V, COUT = CIN = 10 µF, L = 4.7 µH, VOUT = 3.3V, IOUT = 0 mA, TA = +25°C. Boldface specifications apply over the TA range of -40 oC to +85oC. Parameters Sym Min Typ Max Units Conditions Note 1: 3.3 k resistive load, 3.3V OUT (1 mA). 2: For VIN > VOUT, VOUT will not remain in regulation. 3: IQOUT is measured at VOUT, VOUT is external supplied for VOUT > VIN (device is not switching), IQIN is measured at VIN pin during Sleep period, no load. 4: 220 resistive load, 3.3V OUT (15 mA). 5: Determined by characterization, not production tested. TEMPERATURE SPECIFICATIONS Electrical Characteristics: Unless otherwise indicated, VIN = 1.5V, COUT = CIN = 10 µF, L = 4.7 µH, VOUT = 3.3V, IOUT = 0 mA. Parameters Sym Min Typ Max Units Conditions Temperature Ranges Operating Temperature Range TJ -40 — +85 °C Steady State Storage Temperature Range TA -65 — +150 °C Maximum Junction Temperature TJ — — +150 °C Transient Package Thermal Resistances Thermal Resistance, 5L-SOT-23 JA — 220.7 — °C/W EIA/JESD51-3 Standard Thermal Resistance, 8L-2x3 TDFN JA — 52.5 — °C/W |
