Common Characteristics
Output 1 Characteristics: Step-Up Controller
XC9502B093
Output 2 Characteristics: Step-Down Controller
*1 : Although the IC's step-up operations start from a V
DD
of 0.8V, the output voltage and switching frequency are stabilized at V
DD
2.0V. Therefore, a V
DD
of more than 2.0V is recommended when V
DD
is supplied from V
IN
or other power sources.
*2 : Although the IC's switching operations start from a V
IN
of 0.9V, the IC's power supply pin (V
DD
) and output voltage monitor pin
(FB1) should be connected to V
OUT1
. With operations from V
IN
=0.9V, the 2nd channel's (output 2) EN2 pin should be set to
chip disable. Once output voltage V
OUT1
is more than 2.0V, the EN2 pin should be set to chip enable.
*3 : Please be careful not to exceed the breakdown voltage level of the external components.
*4 : EFFI={ [ (output voltage)
(output current) ] / [ (input voltage)
(input current) ] }
