Introduction

AI Translation

OBGZ10 is a highly integrated current mode PWM control IC optimized for high performance, low standby power and cost effective offline flyback converter applications. The OBGZ10 is a highly integrated PWM controller IC optimized for offline flyback converter applications in sub 30W power range. The extended burst mode control greatly reduces the standby power consumption and helps the design easily meet the international power conservation requirements.

Features

AI Translation
  • PWM switching frequency at normal operation is externally programmable and trimmed to tight range.
  • At no load or light load condition, the IC operates in extended ‘burst mode’ to minimize switching loss.
  • VDD low startup current and low operating current contribute to a reliable power on startup design.
  • OBGZ10 offers complete protection coverage with automatic self-recovery feature including Cycle-by-Cycle current limiting (OCP), over load protection (OLP), VDD over voltage clamp and under voltage lockout (UVLO).
  • The Gate-drive output is clamped to maximum 18V to protect the power MOSFET.
  • Excellent EMI performance is achieved with OnBright proprietary frequency shuffling technique together with soft switching control at the totem pole gate drive output.
  • Tone energy at below 20KHz is minimized in the design and audio noise is eliminated during operation.
  • OBGZ10 is offered in SOT23-6 package.
  • On-Bright Proprietary Frequency Shuffling Technology for Improved EMI Performance.
  • Extended Burst Mode Control For Improved Efficiency and Minimum Standby Power Design.
  • Audio Noise Free Operation.
  • External Programmable PWM Switching Frequency.
  • Low VDD Startup Current and Low Operating Current (1.6mA).
  • Good Protection Coverage With Auto Self-Recovery:
    • VDD Over Voltage Clamp and Under Voltage Lockout with Hysteresis (UVLO).
    • Gate Output Maximum Voltage Clamp (18V).
    • On-Bright Proprietary Line Input Compensated Cycle-by-Cycle Over-current Threshold Setting For Constant Output Power Limiting Over Universal Input Voltage Range.
    • Overload Protection (OLP).
