PM8804TR

PWM peak current mode controller for PoE and telecom systems

ECCN USEAR99
ECCN EUNEC
Packing TypeTape And Reel
RoHs compliantEcopack2
GradeIndustrial
Package NameVFQFPN 16 3x3x1.0

The PM8804 is a PWM controller that integrates all the circuitry required to design a smart and efficient 48 V converter for PoE and telecom mid-power applications.

Key features
  • PWM peak current mode controller
  • Input operating voltage up to 75 V
  • Internal high-voltage start up regulator with 20 mA current capability
  • Current sense with programmable blanking time up to 200 ns
  • Programmable fixed frequency up to 1 MHz
  • Soft-start up with settable time
  • Soft turn off (optionally disabled)
  • Dual low-side complementary gate drivers
  • Programmable dead time from 10 to 200 ns between GATE1 and GATE2
  • Gate drivers have 1 A peak capability
  • GATE2 optionally turned off for reduced consumption
  • 80% maximum duty cycle with internal slope compensation
  • Internal pull-up resistor on CTL pin enables the optocoupler connection
  • Operating current consumption & 1.5 mA
  • Embedded protections:
    • Severe overcurrent protection with latch after 4 events
    • Delayed overload protection with automatic restart
    • Feedback disconnection (OV) protection on VC
    • Thermal shutdown
  • High efficiency topologies:
    • Flyback, forward
    • Flyback with synchronous rectification
    • Flyback with active clamp
    • Forward with active clamp
