ISL6236

Product Description

The ISL6236 dual step-down, switch-mode power-supply (SMPS) controller generates logic-supply voltages in battery-powered systems. The ISL6236 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 SMPS2 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.

Features:

• Wide Input Voltage Range 5.5V to 25V
• Dual Fixed 1.05V/3.3V and 1.5V/5.0V Outputs or Adjustable 0.7V to 5.5V (SMPS1) and 0V to 2.5V (SMPS2), ±1.5% Accuracy
• Secondary Feedback Input (Maintains Charge Pump Voltage)
• 1.7ms Digital Soft-Start and Independent Shutdown
• Fixed 3.3V/5.0V, or Adjustable Output 0.7V to 4.5V, ±1.5% (LDO): 200mA
