BU9000xGWZ Series Step-Down Switching Regulators

High efficiency buck switching regulators with built-in power MOSFET from ROHM

Image of ROHM Semiconductor's BU9000xGWZ Series Step-Down Switching Regulators

ROHM’s BU9000xGWZ series of 6 MHz synchronous step-down switching regulators delivers up to 1.0 A of load current (VIN 3.0 to 5.5 V) and features both fixed PWM mode as well as automatic PWM/PFM switching operation for superior efficiency across the entire load region. (PFM mode is typically used to minimize current consumption while ensuring high efficiency at light loads.)

In addition, the ultra-compact form-factor reduces space by 20% over conventional units, meeting the need for a smaller footprint in today’s high performance, space-constrained power supply applications.

Features
  • Fast transient response
  • Automatic PFM/PWM mode switching
  • Forced PWM mode
  • Soft-start function
  • Undervoltage lock out function (UVLO)
  • Overcurrent protection circuit
  • Thermal shut down circuit (TSD)
  • Ultra-compact package (1.33 mm x 0.90 mm x 0.40 mm)
