Typical numbers are for information only. (2) Verified by design and not tested in production. (3) Start-up time is measured from the moment boost is activated until the VBOOST crosses 90% of its target value. (4) 1.8 A is the maximum ISW_LIM supported with the DSBGA package. For applications requiring the ISW_LIM to be greater than 1.8 A and up to 2.6 A, WQFN package should be considered. 7.6 Electrical Characteristics — Boost Converter over operating free-air temperature range (unless otherwise noted) (1) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT RDS_ON Switch ON resistance ISW = 0.5A 0.19 Ω VBOOST_MIN Boost minimum output voltage VBOOST_RANGE = 0 VBOOST_RANGE = 1 7 16 V VBOOST_MAX Boost maximum output voltage VBOOST_MAX = 100, VBOOST_RANGE = 0 VBOOST_MAX = 101, VBOOST_RANGE = 0 VBOOST_MAX = 110, VBOOST_RANGE = 0 VBOOST_MAX = 111, VBOOST_RANGE = 0 19 24.0 28.0 32 21 25 30 34 22 27 32 37 V VBOOST_MAX = 010, VBOOST_RANGE = 1 VBOOST_MAX = 011, VBOOST_RANGE = 1 VBOOST_MAX = 100, VBOOST_RANGE = 1 VBOOST_MAX = 101, VBOOST_RANGE = 1 VBOOST_MAX = 110, VBOOST_RANGE = 1 VBOOST_MAX = 111, VBOOST_RANGE = 1 17.9 22.8 27.8 32.7 37.2 41.8 21 25 30 34.5 39 43 23.1 27.2 31.5 36.6 40.8 44.2 V ILOAD_MAX Maximum continuous output load current VIN = 3 V, VOUT = 18 V 220 mA VIN = 3 V, VOUT = 24 V 160 VIN = 3 V, VOUT = 30 V 120 VOUT/VIN Conversion ratio(2) fSW = 625 kHz 15 fSW = 1250 kHz 12 fSW Switching frequency BOOST_FREQ = 00 BOOST_FREQ = 01 BOOST_FREQ = 10 312 625 1250 kHz VOVP Overvoltage protection voltage VBOOST_RANGE = 1 VBOOST + 1.6 V VUVLO VIN undervoltage lockout threshold UVLO_EN = 1 V UVLO_TH = 0, falling UVLO_TH = 1, falling 2.5 5.2 VUVLO_hyst VUVLO hysteresis VUVLO[rising] VUVLO[falling] UVLO_TH = 0 50 mV UVLO_TH = 1 100 tPULSE Switch minimum pulse width No load 50 ns tSTARTUP Start-up time See(3) 8 ms ISW_LIM SW pin current limit(4) IBOOST_LIM_2X = 0 IBOOST_LIM = 00 IBOOST_LIM = 01 IBOOST_LIM = 10 IBOOST_LIM = 11 0.66 0.88 1.12 1.35 0.9 1.2 1.5 1.8 1.16 1.40 1.73 2.07 A IBOOST_LIM_2X = 1 IBOOST_LIM = 00 IBOOST_LIM = 01 IBOOST_LIM = 10 1.6 2.1 2.6 A ΔVSW / toff_on SW pin slew rate during OFF to ON transition EN_DRV3 = 0 AND EN_DRV2 = 0 EN_DRV3 = 0 AND EN_DRV2 = 1 EN_DRV3 = 1 AND EN_DRV2 = 1 3.7 5.3 7.5 V/ns ΔVSW / ton_off SW pin slew rate during ON to OFF transition EN_DRV3 = 0 AND EN_DRV2 = 0 EN_DRV3 = 0 AND EN_DRV2 = 1 EN_DRV3 = 1 AND EN_DRV2 = 1 1.9 4.4 4.8 V/ns ΔtON / tSW Peak-to-peak switch ON time deviation to SW period ratio (spread spectrum feature) SSCLK_EN = 1 1% |
