ISL6235 - Advanced Triple PWM Only Mode and Dual Linear Power Controller

General Description

Supplies all the power necessary to operate the chip.

The IC starts to operate when the voltage on this pin exceeds 4.7V and stops operating when the voltage on this pin drops below approximately 4.5V.

Key Features

  • PWM Only Mode for Reduced Noise at Light Loads.
  • Provides Five Regulated Voltages - +5V ALWAYS - +3.3V ALWAYS - +5V Main - +3.3V Main - +12V.
  • High Efficiency Over Wide Line and Load Range - Synchronous Buck Converters on Main Outputs.
  • No Current-Sense Resistor Required - Uses MOSFET’s rDS(ON) - Optional Current-Sense Resistor for More Precision.
  • Operates Directly From Battery 5.6 to 24V Input.
  • Input Undervoltage Lock-Out (UVLO).
  • Exce.

The IC integrates three fixed frequency pulse-width-modulation (PWM) controllers and two linear regulators along with monitoring and protection circuitry into a single 24 lead SSOP package. The two PWM controllers that regulate the system main 5V and 3.3V voltages are implemented with synchronousrectified buck converters.
