PARAMETER TEST CONDITIONS MIN TYP MAX UNIT VIN1/VIN2 Terminal UVLO threshold 2.4 2.65 V UVLO hysteresis 110 mV PG1/PG2 Terminal Minimum input voltage for valid PGx I(PGx) = 300 mA, V(PGx) ≤ 0.8 V 1.0 1.3 V Trip threshold voltage VO decreasing 92 95 98 %VOUT Hysteresis voltage Measured at VO 0.5 %VOUT tr(PGx) Rising edge deglitch 30 ms Output low voltage VIN = 2.7V, I(PGx) = 1 mA 0.15 0.4 V Leakage current V(PGx) = 6V 1 mA EN1/EN2 Terminal High-level ENx input voltage 2 V Low-level ENx input voltage 0.7 V Input current (ENx) –1 1 mA MR Terminal High-level input voltage 2 V Low-level input voltage 0.7 V Pull-up current source 6 mA VOUT1 Terminal IO = 1 A, VIN1 = 3.2 V TJ = +25°C 160 Dropout voltage(4) mV IO = 1 A, VIN1 = 3.2 V 250 Peak output current 2 ms pulse width 1.2 A Discharge transistor current VOUT1 = 1.5 V 7.5 mA VOUT2 Terminal Peak output current 2 ms pulse width 3 A Discharge transistor current VOUT2 = 1.5 V 7.5 mA FB Terminal Input current: TPS70402 FB = 1.8 V 1 mA (4) Input voltage (VIN1 or VIN2) = VO(typ) – 100 mV. For 1.5-V, 1.8-V, and 2.5-V regulators, the dropout voltage is limited by input voltage range. The 3.3-V regulator input is set to 3.2 V to perform this test. 6 Submit Documentation Feedback Copyright © 2000–2010, Texas Instruments Incorporated |
