The ISL85410 and ISL85418 are integrated synchronous buck regulators with a wide input voltage range of 3 V to 40 V. They have integrated MOSFETs (RDS(ON) of 250/90 mΩ), a bootstrap diode, and internal compensation for a compact solution size. The switching frequency is adjustable from 300 kHz to 2 MHz and can be synchronized with an external clock. Features include adjustable soft-start, enable, power-good, and full protection, including over current (OC), over and under voltage (OV and UV), under voltage lockout (UVLO), and over temperature. The ISL85415 has an input voltage range of 3 V to 36 V and RDS(ON) of 450/250 mΩ, but otherwise has the same features as the other two devices. These devices provide simplicity and reliability for mid to low current applications at high voltages. The adjustable features also allow for some design flexibility.
