Overview
The AP2001SL-13 is a PWM control circuit integrated into a single chip, primarily designed for power-supply regulator applications. It operates within an input voltage range of 3.6V to 40V and supports a switching frequency of 500kHz. The device functions as a buck converter controller with an operating temperature range from -20°C to +85°C. It features a maximum output current capability of 20mA for its control interface. The component is housed in a 16-pin SOP package.
Feature Summary
- Integrates Pulse-width-Modulation (PWM) control circuitry into a single chip design
- Supports buck converter topology for power-supply regulation
- Operates with wide input voltage range up to 40V
Applications
- Power-supply regulators
- Buck converter designs
- DC-DC conversion systems
Procurement Notes
Verify the specific pinout and thermal characteristics against the official Diodes Incorporated datasheet before finalizing the PCB layout. Ensure that the selected heat dissipation method aligns with the SOP-16L package limitations under maximum load conditions. Confirm that the 500kHz switching frequency matches the requirements of the external inductor and capacitor selection for optimal efficiency and stability.
Selection Notes
Select this component when a dedicated PWM controller is required for buck applications rather than an integrated switch regulator. Consider the 40V maximum input rating and 500kHz frequency for compatibility with available passive components. Evaluate the SOP-16L package size constraints against the available board space. Verify that the 20mA control current is sufficient for the intended gate drive or feedback network configuration.
Part Context
The AP2001 series represents Diodes Incorporated's solution for standalone PWM control in power supply designs. Unlike integrated power switches, this part focuses on the control logic, allowing designers to select external MOSFETs based on specific current and voltage needs. This flexibility supports customized power stages while maintaining precise regulation through internal PWM circuitry.
Replacement Considerations
Direct replacements must match the 16-pin SOP package and 500kHz PWM operation. Verify that alternative controllers support the same 3.6V-40V input range and provide compatible feedback pin configurations. Check if the substitute offers similar protection features such as over-current or thermal shutdown if required by the application.
