Product Specification  
IXD3235/36/37  
5) A 10μA (maximum) current may leak at high temperature  
6) The CE/MODE pin of the IXD3237A series functions also as an external switching pin between PWM and PWM/PFM control. Control  
is switched to the automatic PWM/PFM switching mode when the CE/MODE pin voltage is equal to or greater than VIN minus 0.3 V,  
and to the PWM mode when the CE/MODE pin voltage is equal to or lower than VIN minus 1.0V. However, it should be equal to or  
greater than VCEH  
7) Time from moment when VOUT is shorted to GND via 1 Ω resistor to the moment, when Current Limit generates pulse stopping LX  
oscillations  
8) When VIN is less than 2.4 V, current limit may not be reached because of voltage drop across ON resistance  
9) When the difference between input and output voltage is small, some cycles may be skipped completely before current maximizes. If  
load current increases in this state, output voltage will decrease because of the voltage drop across P-channel transistor  
10) Current limit denotes the level of an inductor peak current  
11) Voltage, when LX pin voltage is “L”=+0.1 V ~ -0.1 V  
12) Not for IXD3235 series, because they have PWM mode only  
13) The IXD3237 series only  
14) Voltage at which LX pin state changes from “L” to “H” = VIN ~ VIN - 1.2 V”  
15) Voltage at which LX pin state changes from “H” to “L” ”=+0.1 V ~ -0.1 V  
16) Voltage at which VOUT becomes more than VIN, while VIN is rising from 0 V to VOUT (E) x 0.5 V
