Buck DC/DC Converter + Low Noise LDO 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. Moreover, the integrated LDO provides an auxiliary output supply for noise sensitive circuit. Features ■ Power.
■ 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 with VO1/VIN1 ≤ 80 % (IO1 ≤ 10 mA) (CH1)
■ Power-on-reset with 66 ms delay (CH1)
■ Built-in short circuit protect (CH2)
