General Description

The BL9352A is a wide input range, highefficiency, and high frequency DC-to-DC stepdown switching regulator, capable of delivering up to 0.6A of output current.

With a fixed switching frequency of 1.6MHz, 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 45V, with even higher transient voltages.

Key Features

  • Wide Input Operating Range from 4.5V to 45V.
  • 420mΩ internal NMOS.
  • Up to 95% Efficiency at 16V in 12V out L=47uH with 300mA loading.
  • Internal compensation.
  • Capable of Delivering 600mA continuous output current.
  • Fixed 1.6MHz PWM operation.
  • Internal soft start.
  • Output voltage adjustable down to 0.795V.
  • Cycle-by-cycle current limit.
  • Current Mode control.
  • Short-circuit protection.
  • Logic Control Shutdown EN can be short to VIN.
  • Thermal.
