ISL97536
Monolithic 1A Step-Down Regulator with Low Quiescent Current
FN6279 Rev 1.00 November 2, 2007
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-OnReset 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.
