MAX5068 Datasheet (Maxim Integrated Products)

MAX5068, Current-Mode PWM Controller

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.

Isolated or nonisolated power supplies are easily constructed using either primary- or secondary-sid

MAX5068 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 1.2
