Description
The MAX5068 is a high-frequency, current-mode, pulse-width modulation (PWM) controller that integrates all the building blocks necessary for implementing ACDC or DC-DC fixed-frequency power supplies.
Features
- an accurate externally programmable oscillator that simplifies system design. An input undervoltage lockout (UVLO) programs the input-supply startup voltage and ensures proper operation during brownout conditions. A single external resistor programs the output switching frequency from 12.5kHz to 1.25MHz. The MAX5068A/ B/C/E provide a SYNC input for synchronization to an external clock. The maximum FET-driver duty cycle is www. DataSheet4U. com 50% for the MAX5068A/B and 75% for the MAX5068C/ D/E/F.
