µPD168830 is a low-cost power supply control IC with a single constant-current controller/driver channel, ideally suited to general lighting and illumination, as well as street lighting. A high current drive of up to 1,500 mA is supported by providing an external power MOSFET. Furthermore, operating conditions for either step-up or step-down operation can be selected and used according to the configuration of external components and settings of selected pins. The µPD168830 has separate circuits for protecting against overheating, low voltages, overcurrents, and overvoltages (step-up operation only), and can control load current by externally inputting PWM signals.

Features:

  • Supports high current by selecting an external power MOSFET (1,500 mA MAX.)
  • Enables selection of step-up or step-down operation
  • Wide input voltage range (9 to 38 V)
  • Can perform on/off control of load current by using PWM signal and setting of load current value by using external resistors
  • On-chip overcurrent protection function
  • On-chip overvoltage protection function (during step-up operation only)
  • Low-voltage protection function
  • Driver IC overheat protection circuit
  • Equipped with standby (enable) pin
