Beschreibung

BD9A302QWZ is a synchronous buck DC/DC
converter with built-in low on-resistance power
MOSFETs. This IC is capable of providing current up
to 3A. The SLLMTM control provides excellent
efficiency characteristics in light-load conditions which
make the product ideal for equipment and devices that
demand minimal standby power consumption. The
oscillating frequency is high at 1MHz using a small
value of inductor. BD9A302QWZ is a current mode
control DC/DC converter and features high-speed
transient response. Phase compensation can also be
set easily.
