MB39C022G - Buck DC/DC Converter + Low Noise LDO

General Description

The MB39C022 is a 2 channels power supply IC.

It consists of one channel Buck DC/DC Converter and one channel LDO regulator.

The DC/DC converter has fast transient response with current mode control topology.

Key Features

  • Power supply voltage range : 2.5 V to 5.5 V.
  • For Buck DC/DC included SW FET (CH1) : output 0.8 V to 4.5 V, 600 mA Max DC.
  • For LDO (CH2) : output 3.30 V (MB39C022G) 300 mA Max DC : output 2.85 V (MB39C022J) 300 mA Max DC : output 1.80 V (MB39C022L) 300 mA Max DC : output 1.20 V (MB39C022N) 300 mA Max DC.
  • Error amplifier threshold voltage : 0.3 V ± (2.5 %) (CH1).
  • Fast line transient response with current mode topology (CH1).
  • PFM mode at light load current wi.
