AF5602 - Synchronous Step-Down Converter

Download the AF5602 datasheet PDF. This datasheet also covers the AF5602-Alfa variant, as both devices belong to the same synchronous step-down converter family and are provided as variant models within a single manufacturer datasheet.

General Description

AF5602 is a wide input voltage, high efficiency Active CC step-down DC/DC converter that operates in either CV (Constant Output Voltage) mode or CC (Constant Output Current) mode.

AF5602 provides up to 2.5A output current at 180kHz switching frequency.

Key Features

  • Wide 8V to 38V Operating Input Range Integrated 140mΩ Power MOSFET Switches Output Adjustable from VFB(1.0V) to 5.5V Up to 92% Efficiency Internal Soft-Start Stable with Low ESR Ceramic Output Capacitors Fixed 180KHz Frequency Cycle-by-Cycle Over Current Protection Input Under Voltage Lockout.

Alfa-MOS Technology AF5602 Synchronous 180KHz, 2A / 38V Step-Down Converter With CC / CV General Description AF5602 is a wide input voltage, high efficiency Active CC step-down DC/DC converter that operates in either CV (Constant Output Voltage) mode or CC (Constant Output Current) mode. AF5602 provides up to 2.5A output current at 180kHz switching frequency. Current mode control provides fast transient response and cycle-by-cycle current limit. An internal soft-start prevents inrush current at turn-on, This device, available in an SOP-8EP(Exposed Pad) package, provides a very compact solution with minimal external components. Features Wide 8V to 38V Operating Input Range Integrated 140mΩ Power MOSFET Switches Output Adjustable from VFB(1.0V) to 5.
