GENERAL DESCRIPTION

The BL9362 is a wide input range,high-efficiency,and high frequency DC-to-DC step-down switching regulator,capable of delivering up to 0.6A of output current.With a fixed switching frequency of 2MHz,this current mode PWM controlled converter allows the use of small external components,such as ceramic input and output caps,as well as small inductors.

Including cold crank and double battery jumpstarts,the minimum input voltage may be as low as 4.5V and the maximum up to 60V,with even higher transient voltages.With these high input voltages,linear regulators cannot be used for high supply currents without overheating the regulator.Instead,high efficiency switching regulators such as BL9362 must be used to minimize thermal dissipation.

BL9362 is available SOT23-6 Packages.
