PARAMETER CONDITIONS MIN TYP MAX UNITS SYNC Range Internal oscillator nominal frequency must be set to half of the SYNC frequency 1000 2800 kHz High 100 SYNC Input Pulse Width (Note 3) Low 100 ns SYNC Rise/Fall Time (Note 3) 100 ns ERROR AMPLIFIER FB_ Input Bias Current 250 nA FB_ Input Voltage Set Point 0.99 1.00 1.01 V 0°C to +85°C 1.25 1.8 2.70 FB_ to COMP_ Transconductance -40°C to +85°C 1.2 1.8 2.9 mS DRIVERS DL_, DH_ Break-Before-Make Time CLOAD = 5nF 30 ns Low 1.5 2.5 DH_ On-Resistance High 3 5 Ω Low 0.6 1.5 DL_ On-Resistance High 3 5 Ω LOGIC INPUTS (EN, SYNC) Input Low Level Typical 15% hysteresis, VL = 4.75V 0.8 V Input High Level VL = 5.5V 2.4 V Input High/Low Bias Current VEN = 0 or 5.5V -1 +0.1 +1 µA LOGIC OUTPUTS (CKO) Output Low Level VL = 5V, sinking 5mA 0.4 V Output High Level VL = 5V, sourcing 5mA 4.0 V COMP_ Pulldown Resistance During Shutdown and Current Limit 17 Ω RST OUTPUT Output-Voltage Trip Level Both FBs must be over this to allow the reset timer to start; there is no hysteresis 0.87 0.9 0.93 V VL = 5V, sinking 3.2mA 0.4 Output Low Level VL = 1V, sinking 0.4mA 0.3 V Output Leakage V+ = VL = 5V, V RST = 5.5V, VFB = 1V 1 µA Reset Timeout Period VFB_ = 1V 140 315 560 ms FB_ to Reset Delay FB_ overdrive from 1V to 0.85V 4 µs Note 1: Specifications to -40°C are guaranteed by design and not production tested. Note 2: Operating supply range is guaranteed by VL line regulation test. Connect V+ to VL for 5V operation. Note 3: Guaranteed by design and not production tested. |
