Semiconductor?The SB2100 with Schottky Barrier Diodes (SBD) DO-15 RoHS manufactured by GD Semiconductor is a 1A switch-mode step-down switching regulator with adjustable output voltage. It features an integrated dual-channel SBD for efficiency and low on-resistance, providing excellent load and line regulation. The device can deliver a highly efficient output of up to 98.5% in a wide input range from 4.5V to 40V. It can provide up to 1A continuous output current and has programmable soft-start and adjustable switching frequency. The device features a variety of safety measures to protect against under-voltage, over-voltage, over-temperature, and over-current conditions, for a reliable and safe operation. The RoHS-compliant package makes it suitable for lead-free designs.
