The AP1509-33SG-13 from Diodes Incorporated is a monolithic IC designed as a step-down DC-DC converter. It is capable of driving a 2A load without requiring an external transistor, saving valuable board space. This device features a fixed output voltage of 3.3V and operates with a switching frequency of 150kHz, allowing for smaller filter components.
The converter operates within an input voltage range of 4.5V to 22V. It includes built-in protection features such as thermal shutdown and current-limit protection to prevent damage during over-temperature or over-current conditions. An ON/OFF shutdown control input allows the device to enter a low power standby mode.
Designed for ease of use, the AP1509-33SG-13 utilizes voltage mode non-synchronous PWM control and has internal compensation, eliminating the need for external design. It is supplied in a standard 8-lead SOP package suitable for surface mounting. The device is also noted as being totally lead-free and RoHS 3 compliant.
