HM2259 16V, 2A Synchronous Buck Converter General Description The HM2259 devices are synchronous step-down converters optimized for small solution size and high efficiency. The devices integrate switches capable of delivering an output current up to 2A. The devices are based on an adaptive on time with current mode control scheme. Typical operating frequency is 520 KHz at medium to heavy loads. The devices are 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 from 4.5V to 16V. Power sequencing is possible by configuring the Enable pin.
