ISL6741IVZ-T

Flexible Double Ended Voltage and Current Mode PWM Controllers

开关控制器 CUR PWM MODE CNTRLR 16LD

The ISL6741IVZ-T ISL6740, ISL6741 family of adjustable frequency, low  power, Pulse Width Modulating (PWM) voltage mode  (ISL6740) and current mode (ISL6741) controllers, is designed  for a wide range of power conversion applications using  half-bridge, full bridge and push-pull configurations. These  controllers provide an extremely flexible oscillator that allows  precise control of frequency, duty cycle and dead time.

• Precision duty cycle and dead time control

• 95μA start-up current

• Adjustable delayed overcurrent shutdown and restart (ISL6740)

• Adjustable short-circuit shutdown and restart

• Adjustable oscillator frequency up to 2MHz

• Bidirectional synchronization

• Inhibit signal

• Internal over-temperature protection

• System over-temperature protection using a thermistor or sensor

• Adjustable soft-start

• Adjustable input undervoltage lockout

• Fault signal

• Tight tolerance voltage reference over line, load and temperature

• Pb-free (RoHS compliant)

Applications ISL6741IVZ-T

• Telecom and datacom power
