Product Summary

The ISL6236HRZ is a high-efficiency, quad-output, main power supply controller for notebook computer. The ISL6236HRZ dual step-down, switch-mode power-supply(SMPS) controller generates logic-supply voltages in battery-powered systems. The ISL6236HRZ include two pulse-width modulation (PWM) controllers, 5V/3.3V and 1.5V/1.05V. The output of SMPS1 can also be adjusted from 0.7V to 5.5V. The ISL6236HRZ output can be adjusted from 0V to 2.5V by setting REFIN2 voltage. An optional external charge pump can be monitored through SECFB. This device features a linear regulator providing 3.3V/5V, or adjustable from 0.7V to 4.5V output via LDOREFIN.
