Maxim MAX5022EVKIT

AC/DC，主面5V85 ~ 265 VAC

Overview

The MAX5021/MAX5022EVKIT current-mode PWM controllers contain all the control circuitry required for the design of wide input voltage range isolated power supplies. These devices are well suited for use in universal input (85VAC to 265VAC) off-line or telecom (-36VDC to -72VDC) power supplies.An undervoltage lockout (UVLO) circuit with large hysteresis coupled with low startup and operating current reduce power dissipation in the startup resistor and allow use of ceramic bypass capacitors. The 262kHz switching frequency is internally trimmed to }12% accuracy; this allows the optimization of the magnetic and filter components resulting in compact, cost-effective power supplies. The MAX5021 with 50% maximum duty cycle and MAX5022EVKIT with 75% maximum duty cycle are recommended for forward converters and flyback converters, respectively. The MAX5021/MAX5022EVKIT are available in 6-pin SOT23, 8-pin μMAX, and 8-pin DIP packages and are rated for operation over the -40C to +85C temperature range.
