XN1042 controller equivalent, current mode pwm controller.
* Extended Burst Mode Control For Improved
*Efficiency and Minimum Standby Power Design
loss. Lower standby power and higher conversion
*Audio Noise Free Op.
PWM switching frequency at normal
operation is externally programmable and trimmed to tight range. At no load or light.
The tone energy at below 20KHZ is minimized in
XN1042 is a highly integrated current mode PWM
operation. Consequently, audio noise performance is
control IC optimized for high performance, low standby greatly improved. XN1042 is offered in both S.
