Synchronous Step-Down DC/DC Converter with built-in LDO Regulator in parallel plus Voltage Detector
Preliminary
! ELECTRICAL CHARACTERISTICS (Continued)
# Detector (2.7V product)
Test Conditions :
Unless otherwise stated;
DC/DC : VIN=3.6V [@ DCOUT:1.5V]
VR : VIN = 4.3V (VIN=VROUT(T) + 1.0V)
VD : VIN=6.0V
Common conditions for all test items : CE=VIN, MODE=0V
* VROUT(T) : Setting Output Voltage
note 1: Including hysteresis operating voltage range.
note 2: ON resistance (
Ω)= 0.05 (V) / ILX (A)
note 3: EFFI = { ( Output Voltage x Output Current ) / ( Input Voltage x Input Current) } x 100
note 4: 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 5: Vdif = (VIN1
(note 6) - VROUT1 (note 7 ) )
note 6: VIN 1 = The input voltage when VROUT1 appears as input voltage is gradually decreased.
note 7: VROUT1 = A voltage equal to 98% of the output voltage whenever an amply stabilized IOUT {VROUT(T) + 1.0V} is input.
note 8: Current limit = When VIN is low, limit current may not be reached because of voltage falls caused
by ON resistance or serial resistance of coils.
note 9: Integral latch circuit=latch time may become longer and latch operation may not work when VIN is 3.0V or more.
note 10 : VDR(E) = VD release voltage
note 11
: When temperature is high, a current of approximately 5.0µA (maximum) may leak.
note 12 : When using the IC with a regulator output at almost no load, a capacitor should be placed as close as possible between
AVDD and AGND (CIN2), connected with low impedance. Please also see the recommended pattern layout
on page 13 for your reference. Should it not be possible to place the input capacitor nearby, the regulated output level
may increase up to the VDD level while the load of the DC/DC converter increases and the regulator output is at almost no load.
