HM3410 - 1.2A synchronous rectification Buck converter

Description

The HM3410 is a high-efficiency synchronous Buck converter that can operate over a wide input voltage range of 2.5V to 5.5V and can deliver up to 1.2A of output current.

It integrates the main switch and synchronous switch inside, and has extremely low on-resistance to reduce conduction loss.

Features

  • 2.5V~5.5V input voltage range.
  • 35uA ultra-low quiescent current.
  • Internal soft-start reduces chip stress.
  • Short circuit protection Hiccup mode.
  • Internal integrated low RDS(ON) switch.
  • 1.5MHz switching frequency minimizes external components.
  • Optimized PFM mode for battery.

HM3410 High efficiency, 1.2A synchronous rectification Buck converter with built-in switch General Description The HM3410 is a high-efficiency synchronous Buck converter that can operate over a wide input voltage range of 2.5V to 5.5V and can deliver up to 1.2A of output current. It integrates the main switch and synchronous switch inside, and has extremely low on-resistance to reduce conduction loss. The switching frequency is 1.5MHz, which can reduce the size of the external inductor and output capacitor and reduce the output voltage ripple. The HM3410 is available in SOT23-5 / SOT23-6 / DFN2X2-6L package. Features  2.5V~5.
