PFM mode 19 29 mA enabled (Mode = 0) device not switching, EN1 = 1 OR EN2 = 1 Two converter, IOUT = 0mA. PFM mode 32 48 mA enabled (Mode = 0) device not switching, IQ Operating quiescent current EN1 = 1 AND EN2 = 1 IOUT = 0mA, MODE/DATA = GND, for one 23 mA converter, VOUT 1.575V (1) IOUT = 0mA, MODE/DATA = VIN, for one 3.6 mA converter, VOUT 1.575V (1) EN1, EN2 = GND, VIN = 3.6V (2) 1.2 3 ISD Shutdown current mA EN1, EN2 = GND, VIN ramped from 0V to 0.1 1 3.6V(3) Falling 1.5 2.35 VUVLO Undervoltage lockout threshold V Rising 2.4 ENABLE EN1, EN2 VIH High-level input voltage, EN1, EN2 1.2 VIN V VIL Low-level input voltage, EN1, EN2 0 0.4 V IIN Input bias current, EN1, EN2 EN1, EN2 = GND or VIN 0.05 1.0 mA DEF_1 INPUT DEF_1 pin is a digital input at TPS62401 VDEF_1H DEF_1 high level input voltage 0.9 VIN V fixed output voltage option DEF_1 pin is a digital input at TPS62401 VDEF_1L DEF_1 low level input voltage 0 0.4 V fixed output voltage option IIN Input bias current DEF_1 DEF_1 GND or VIN 0.01 1.0 mA MODE/DATA VIH High-level input voltage, MODE/DATA 1.2 VIN V VIL Low-level input voltage, MODE/DATA 0 0.4 V IIN Input bias current, MODE/DATA MODE/DATA = GND or VIN 0.01 1.0 mA VOH Acknowledge output voltage high Open drain, via external pullup resistor VIN V VOL Acknowledge output voltage low Open drain, sink current 500mA 0 0.4 V INTERFACE TIMING tStart Start time 2 ms tH_LB High time low bit, logic 0 detection Signal level on MODE/DATA pin is > 1.2V 2 200 ms (1) Device is switching with no load on the output, L = 3.3mH, value includes losses of the coil (2) These values are valid after the device has been already enabled one time (EN1 or EN2 = high) and supply voltage VIN has not powered down. (3) These values are valid when the device is disabled (EN1 and EN2 low) and supply voltage VIN is powered up. The values remain valid until the device has been enabled first time (EN1 or EN2 = high). After first enable, Note 3 becomes valid.
