General 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. Isolated or nonisolated power supplies are easily constructed using either primary- or secondary-side regulation

FEATUREs
♦ Current-Mode Control with 47µA (typ) Startup Current
♦ Resistor-Programmable ±4.5% Accurate Switching Frequency: 25kHz to 1.25MHz (MAX5068A/B) 12.5kHz to 625kHz (MAX5068C/D/E/F)
♦ Rectified 85VAC to 265VAC or 36VDC to 72VDC Input (MAX5068A/C/D)
♦ Input Directly Driven from 10.8V to 24V (MAX5068B/E/F)
♦ Frequency Synchronization Input (MAX5068A/B/C/E)
♦ Programmable Dead Time and Slope Compensation
♦ Programmable Startup Voltage (UVLO)
♦ Programmable UVLO Hysteresis (MAX5068A/B/D/F)
♦ Integrating Fault Protection (Hiccup)
♦ -40°C to +125°C Automotive Temperature Range
♦ 16-Pin Thermally Enhanced TSSOP-EP Package
