Synchronous Step-Down DC/DC Converter with Built-In LDO Regulator In Series plus Voltage Detector
Preliminary
! ELECTRICAL CHARACTERISTICS (Continued)
$ Detector (2.7V product)
Test Conditions :
Unless otherwise stated;
* VROUT(T) : Setting Output Voltage
DC/DC : VIN=3.6V [@ DCOUT:2.2V]
VD : VIN=6.0V
VR : VIN = VROUT(T) + 1.0 (V) [When VROUT(T) <1.4V, VIN =2.4V]
note 1 : VD operates when in stand-by mode.
note 2 : Including hysteresis operating voltage range.
note 3 : On resistance = 0.05V / ILX
note 4 : EFFI = { ( Output Voltage x Output Current ) / ( Input Voltage x Input Current) } x 100
note 5 : Time until it short-circuits DCOUT with GND through 1
Ω of resistance from a state of operation
and is set to DCOUT=0V from current limit pulse generating.
note 6 : Vdif = (VIN1
(note 7) - VROUT1 (note 8 ) )
note 7 : VIN 1 = The input voltage when VROUT1 appears as input voltage is gradually decreased.
note 8 : VROUT1 = A voltage equal to 98% of the output voltage whenever an amply stabilized IOUT {VROUT(T) + 1.0V} is input.
