SY8120BABC - Synchronous Step-Down Regulator

Download the SY8120BABC datasheet PDF. This datasheet also covers the SY8120B variant, as both devices belong to the same synchronous step-down regulator family and are provided as variant models within a single manufacturer datasheet.

Description

SY8120B develops high efficiency synchronous stepdown DC-DC converter capable of delivering 2A load current .

SY8120B operates over a wide input voltage range from 4.5V to 18V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.

Features

  • Low RDS(ON) for internal switches (top/bottom):145/135 m 4.5-18V input voltage range 2A load current capability Instant PWM architecture to achieve fast transient responses Internal softstart limits the inrush current 2% 0.6V reference RoHS Compliant and Halogen Free Compact package: SOT23-6.

Application Note: AN_SY8120B High Efficiency Fast Response, 2A, 18V Input Synchronous Step Down Regulator General Description SY8120B develops high efficiency synchronous stepdown DC-DC converter capable of delivering 2A load current . SY8120B operates over a wide input voltage range from 4.5V to 18V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. SY8120B adopts the instant PWM architecture to achieve fast transient responses for high step down applications and high efficiency at light loads. In addition, it operates under heavy load conditions to minimize the size of inductor and capacitor.
