Details
The IMP690A/IMP692A/IMP802L/IMP802M/IMP805L simplify power supply monitoring and control in microprocessor systems. Each circuit implements four functions: Reset control, watchdog monitoring, batterybackup switching and power-failure monitoring. In addition to microprocessor reset under powerup and power-down conditions, these devices provide battery-backup switching to maintain control in powerloss and brown-out situations. Additional monitoring capabilities can provide an early warning of unregulated power-supply loss before the voltage regulator drops out.

FAQs
What is MP6903?
The MP6903 is a high-frequency, synchronous rectified, step-down switch mode converter designed by Monolithic Power Systems. It is ideal for applications requiring efficient power conversion, such as DC-DC power supplies, LED lighting, and portable electronic devices.
How Does MP6903 Work?
The MP6903 works by efficiently converting input voltage into a lower output voltage using a synchronous rectification technique. It utilizes a high-frequency pulse-width modulation (PWM) control scheme to regulate the output voltage with high efficiency. The converter features integrated power MOSFETs for compact and low-heat dissipation designs.
How Many Pins does MP6903 have and What are the Functions of the Pinout Configuration?
The MP6903 is housed in a QFN (Quad Flat No-leads) 20-pin package. The pinout configuration includes:
- VIN: Input voltage pin.
- SW: Switching node connection.
- VOUT: Output voltage pin.
- PGND: Power ground pin.
- AGND: Analog ground pin.
- FB: Feedback input for output voltage control.
- EN: Enable pin for device control.
- SS/TR: Soft-start/Tracking control pin.
- COMP: Compensation pin for loop stability.
- FB2: Secondary feedback input for multi-rail output voltage control.
- RT/CLK: External synchronization and frequency adjust pin.
- SYNC: Synchronization and frequency adjust input pin.
- SS/TR2: Soft-start and tracking control pin for multi-rail output voltage control.
