The CSM5420 is a synchronous buck converter with a wide input voltage range of 4.5V to 16V. This device optimized for small solution size and high efficiency. The device integrates switches capable of delivering an output current up to 2A. The device is based on an adaptive on-time control mode. Typical operating frequency is 520 kHz at medium to heavy loads.

This device employs current limit and thermal shutdown with auto recovery. The device is optimized to achieve very low output voltage ripple even with small external components and feature an excellent load transient response. The low impedance internal MOSFET supports high efficiency operation with wide input voltage range. Power sequencing is possible by configuring the Enable pin.

The device is rated over the -40°C to +125°C temperature range. It is available in the Green SOT-23-6 package.
