Description

The FAN21SV04EMPX is an integrated synchronous Buck Regulator contains both synchronous MOSFETs and a controller/driver with optimized interconnects, which enables designers to solve high-current requirements in a small area with minimal external components. On-board internal 5V regulator enables single-supply operation for input voltages >6.5V. It can be configured to drive multiple slave devices or synchronize to an external system clock. In slave mode, FAN21SV04 may be set up to be free-running in the absence of a master clock signal. External compensation, programmable switching frequency and current-limit features allow for design optimization and flexibility. High-frequency operation allows for all-ceramic solutions. Integration helps minimize critical inductances, making layout simpler and more efficient compared to discrete solutions. Output overvoltage, undervoltage, overcurrent and thermal-shutdown protections help protect the device from damage during fault conditions.
Fully synchronous operation with integrated Schottky diode on low-side MOSFET boosts efficiency
Synchronizable to external clock with master/slave provisions
Power-good signal
Accepts ceramic capacitors on output
External compensation for flexible design
Starts on pre-bias outputs
Integrated bootstrap diode
Over 94% peak efficiency
1% Reference accuracy over temperature
