Ürün Genel Bakış

The LM5041MTC/NOPB is a Pulse Width Modulated (PWM) Controller contains all of the features necessary to implement either current-fed or voltage-fed push-pull or bridge power converters. These cascaded topologies are well suited for multiple output and higher power applications. The LM5041's four control outputs include: the buck stage controls (HD and LD) and the push-pull control outputs (PUSH and PULL). Push-pull outputs are driven at 50% nominal duty cycle at one half of the switching frequency of the buck stage and can be configured for either a specified overlap time (for current-fed applications) or a specified both-off time (for voltage-fed applications). Push-pull stage MOSFETs can be driven directly from the internal gate drivers while the buck stage requires an external driver such as the LM5102. The LM5041 includes a high-voltage start-up regulator that operates over a wide input range of 15 to 100V.
  • Internal start-up bias regulator
  • Programmable line under-voltage lockout (UVLO) with adjustable hysteresis
  • Current mode control
  • Internal error amplifier with reference
  • Dual mode over-current protection
  • Leading edge blanking
  • Programmable push-pull overlap or dead time
  • Internal 1.5A Push-pull gate drivers
  • Programmable soft-start
  • Programmable oscillator with sync capability
  • Precision reference
  • Thermal shutdown
  • Green product and no Sb/Br
Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
