SYH112 High Efficiency, 500kHz, 2A, 16V Input Synchronous Step Down Regulator Preliminary Specification General Description Features The SYH112 is a high efficiency 500 kHz synchronous • low RDS(ON) for internal switches (top/bottom): step-down DC-DC converter capable of delivering 2A 160mΩ/80mΩ current. The SYH112 operates over a wide input • 4.5-18V input voltage range voltage range from 4.5V to 16V and integrates main • 2A output current capability switch and synchronous switch with very low RDS(ON) • 500 kHz switching frequency to minimize the conduction loss. • Instant PWM architecture to achieve fast transient responses. Low output voltage ripple and small external inductor • Internal softstart limits the inrush current and capacitor sizes are achieved with 500 kHz • ±1.5% 0.6V refer
