The SY8284 develops a high efficiency synchronous step-down DC/DC regulator capable of delivering 4A current over a wide input voltage range of 4V to 23V. Silergy-s proprietary Instant-PWM- fast-response, constant-on-time (COT) PWM control method supports high input/output voltage ratios (low duty cycles), and fast transient response maintaining a near constant operating frequency over line, load and output voltage ranges.
 
This control method provides stable operation without complex compensation and even with low ESR ceramic capacitors. Internal 85m- power and 35m- synchronous rectifier switches provide excellent efficiency over a range of applications, especially for low output voltages and low duty cycles. SY8284 also integrates a bypass switch which allows the IC to be powered by external DC source.
 
Cycle-by-cycle current limit, input under voltage lock-out, internal soft-start, output under voltage protection and over voltage protection, and thermal shutdown provide safe operation in all operating conditions. The SY8284 is available in a compact QFN3×3-20 package.
