The device provides a complete power Processors & DSPs Based Equipment management solution in one IC and is fully 2 C serial interface. programmable via an I FEATURES Independent Digital Pulse Width Modulator (DPWM) channels regulate output voltages 3 Channel Step Down Controller and provide all required protection functions Programmable Output Voltage 0.9V-5.1V such as current limiting and over-voltage Programmable 1.5MHz DPWM Frequency protection. Integrated FET Drivers Each output voltage can be programmed from 4.75V to 5.5V and 5.5V to 25V Input 0.9V to 5.1V without the need of an external Voltage Range voltage divider. The wide range of the programmable DPWM switching frequency Up to 5 Reconfigurable GPIO Pins (from 300 kHz to 1.5 MHz) enables the user to 2 Fully Programmable via I C Interface optimize between efficiency and component Independent Digital Pulse Width size. Input voltage range is from 4.75V to Modulator (DPWM) channels 2 25V. An I C bus interface is provided to Complete Monitoring and Reporting program the IC as well as to communicate with the host for fault reporting and handling, Complete Power Up/Down Sequencing power rail parameters monitoring, etc. Full On Board Protection OTP, UVLO, OCP and OVP The device offers a complete solution including independently programmable: soft-start, soft- Built-in 3.3V/5V LDO stop, start-up delay and ramp of each PWM PowerArchitect Design Software regulator.
