Description
The ISL97536 is a synchronous, integrated FET 1A step-down regulator with internal compensation. It operates with an input voltage range from 2. 5V to 6V, which accommodates supplies of 3. 3V, 5V, or a Li-ion battery source. The output can be externally set from 0. 8V to VIN with a resistive divider. The ISL97536 features PWM control with a 1. 4MHz typical switching frequency. The typical no load quiescent current is only 500µA. Additional features include a 100ms Power-On- Reset output, 1µA shutdown current, short-circuit protection, and over-temperature protection. The ISL97536 is available in the 10 Ld MSOP package, making the entire converter occupy less than 0. 15in2 of PCB area with components on one side only. The 10 Ld MSOP package is specified for operation over the full -40°C to +85°C temperature range.
