VIN = 4V, IOUT = 500mA 1ms Time from when output voltage ramp starts to when output voltage reaches 95% of its nominal value with device operating in boost mode. VIN = 3V, IOUT = 500mA 1ms rDISCHG VOUT Soft-Discharge ON-Resistance EN < VIL 110 Ω POWER MOSFET rDSON_P P-Channel MOSFET ON-Resistance IOUT = 200mA, measured with internal test mode 63 mΩ rDSON_N N-Channel MOSFET ON-Resistance IOUT = 200mA, measured with internal test mode 63 mΩ INDUCTOR PEAK CURRENT LIMIT ILIM_MAX Maximum Peak Current Limit 2A THERMAL PROTECTION Thermal Shutdown 150 °C Thermal Shutdown Hysteresis 35 °C LOGIC INPUTS ILEAK Input Leakage 0.013 0.500 µA VIH Input HIGH Voltage 1.4 V VIL Input LOW Voltage 0.4 V NOTES: 6. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization and are not production tested. 7. Quiescent current measurements are taken when the output is not switching. Analog Specifications VIN = VEN = 3.6V, VOUT = 3.3V, L1 = 1µH, C1 = 10µF, C2 = 47µF, TA = +25°C. Boldface limits apply across the recommended operating temperature range, -40°C to +85°C and input voltage range (1.8V to 5.5V).
