XN1042
Description
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.
Key Features
- Extended Burst Mode Control For Improved
- Efficiency and Minimum Standby Power Design loss. Lower standby power and higher conversion
- Audio Noise Free Operation efficiency is thus achieved. VDD low startup current and
- External Programmable PWM Switching Frequency low operating current contribute to a reliable power on
- Internal Synchronized Slope Compensation startup design with XN1042. A large value resistor could
- Low VIN/VDD Startup Current(6.5uA) and Low thus be used in the startup circuit to minimize the standby Operating Current (2.3mA) power. The internal slope compensation improves system
- Leading Edge Blanking on Current Sense Input large signal stability and reduces the possible subharmonic
- Complete Protection Coverage With Auto Self- oscillation at high PWM duty cycle output. Leading-edge Recovery blanking on current sense input removes the signal glitch
- ExternalProgrammable Over Temperature due to snubber circuit diode reverse recovery. This greatly Protection (OTP) helps to reduce the external component count and system
- With or Without Built in VDD OVP for System cost in application. OVP XN1042 offers complete protection coverage with
