ISL70001SRH

The ISL70001SRH is a radiation hardened and SEE hardened high efficiency monolithic synchronous buck regulator with integrated MOSFETs. This single chip power solution operates over an input voltage range of 3V to 5.5V and provides a tightly regulated output voltage that is externally adjustable from 0.8V to ~85% of the input voltage. Output load current capacity is 6A for TJ < +145°C.

The features of ISL70001SRH are as follows: (1)High Efficiency > 90%; (2)Fixed 1MHz Operating Frequency; (3)Operates from 3V to 5.5V Supply; (4)±1% Reference Voltage over Line, Load, Temperature and Radiation; (5)Adjustable Output Voltage.

The electrical characteristics of the ISL70001SRH are: (1)Operating Supply Current: 40mA at VIN = 5.5V, 25 mA at VIN = 3.6V; (2)Shutdown Supply Current: 6 mA at VIN = 5.5V, EN = GND, 3 mA at VIN = 3.6V, EN = GND; (3)Reference Voltage Tolerance: 0.6 V; (4)Output Voltage Tolerance:0 % at VOUT = 0.8V to 2.5V for VIN = 4.5V to 5.5V, VOUT = 0.8V to 2.5V for VIN = 3V to 3.6V, IOUT = 0A to 6A; (5)Feedback (FB) Input Leakage Current: 0 A at VIN = 5.5V, VFB = 0.6V.
