For high current and low voltage applications
Synchronous buck converter module
This product is a synchronous buck switching converter module. The additional components for DC-DC converter are a
PWM control IC, an external inductor, and input and output capacitors.
Features
• 3 chips (high-side MOSFET, low-side MOSFET, MOSFET gate driver- IC) are in 1 package.
• Maximum Input voltage is 19V, it is capable for note-PC applications.
• Under voltage lockout and thermal shut down
• Keeping off low-side MOSFET function. When load current is low, low-side MOSFET is able to been kept off.
Consequently the efficiency increases at low load condition.
• Internal control circuit disable function. The quiescent current is less than 10ЖA.
• High operation frequency
• High output current
• High efficiency
