XC6416

Series

<Input and Output Capacitor>

The XC6416 needs an output capacitor for phase compensation. The requested capacitance values are described in the table

below. The device may go into unstable operation when the output capacitance reduction happens as a result of bias or

temperature drift. Please choose a capacitor with less influence from temperature and bias. Also, please place 1.0μF input

■OPERATIONAL DESCRIPTION

<Output Voltage Control>

The voltage divided by resistors Rx1 & Rx2 is compared with the internal reference voltage by the error amplifier. The

in relation to the level of output current. Further, the IC's internal circuitry can be shutdown via the EN pin's signal.

<GreenOperation>

XC6416C/D/G/H series can be set as a fixed high-speed (HS) mode or a green operation (GO) mode via a signal to the green

operation (GO) pin. The IC operates in the GO mode when the GO pin becomes low level and the IC operates in the fixed

high-speed mode when the GO pin becomes high level. The XC6416A/B/E/F series normally operates in GO mode because

the high speed (HS) mode and the power save (PS) mode according to the level of output current. While having both

high-speed operation and low supply current state, the series can acquire high efficiency. At the HS/PS automatic switching

mode (GO mode), the switching point of the HS mode and the PS mode is being fixed inside the IC. When the output current

mode changes automatically to the HS mode and the IC becomes high speed operation.
