DocumentDocumentAP64200SP-EVM 40V, 2A, Low IQ, Synchronous DC-DC Buck Converter with Programmable Frequency DESCRIPTION The AP64200 is 2A, synchronous buck converter with a wide input voltage range of 3.8V to 40V. The device fully integrates a 160m high-side power MOSFET and a 80m low-side power MOSFET to provide high-efficiency step-down DC-DC conversion. The AP64200 device is easily used by minimizing the external component count due to its adoption of peak current mode control. The AP64200 design is optimized for Electromagnetic Interference (EMI) reduction. The converter features Frequency Spread Spectrum (FSS) with a switching frequency jitter of ±6%, which reduces EMI by not allowing emitted energy to stay in any one frequency for a significant period of time. It also has a proprietary gate driver scheme to resist switching node ringing without sacrificing MOSFET turn-on and turn-off times, which reduces highfrequency radiated EMI noise caused by MOSFET switching. The device is available in a SO-8EP (Standard) package. FEATURES Wide Input Range: 3.8V-40V 2A Continuous Output Current 0.8V ±1% Reference Voltage 25µA Ultralow Quiescent Current (Pulse Frequency Modulation) Adjustable Switching Frequency: 100kHz to 2.2MHz External Clock Synchronization: 100kHz to 2.2MHz Proprietary Gate Driver Design for Best EMI Reduction Frequency Spread Spectrum (FSS) to Reduce EMI Low-Dropout (LDO) Mode Precision Enable Threshold to adjust UVLO Protection Circuitry o Undervoltage Lockout (UVLO) o Output Overvoltage Protection (OVP) o Cycle-by-Cycle Peak Current Limit o Thermal Shutdown Totally Lead-Free & Fully RoHS Compliant Halogen and Antimony Free.

AP64200SP-EVM 40V, 2A, Low IQ, Synchronous DC-DC Buck Converter with Programmable Frequency QUICK START GUIDE The AP64200SP-EVM has a simple layout and allows access to the appropriate signals through test points. To evaluate the performance of the AP64200SP, follow the procedure below: 1. Connect a power supply to the input terminals VIN and GND. Set VIN to 12V. 2. Connect the positive terminal of the electronic load to VOUT and negative terminal to GND. 3. For Enable, to enable IC, place a jumper at JH6 to "ON" position to connect EN pin to VIN through 100K resistor or leave it OPEN. Jump to "OFF" position to disable IC. 4. The evaluation board should now power up with a 5.0V output voltage. 5. Check for the proper output voltage of 5.0V (±1%) at the output terminals VOUT and GND. Measurement can also be done with a multimeter with the positive and negative leads between VOUT and GND. 6. Set the load to 2A through the electronic load. Check for the stable operation of the SW signal on the oscilloscope. Measure the switching frequency. MEASUREMENT/PERFORMANCE GUIDELINES: 1) When measuring the output voltage ripple, maintain the shortest possible ground lengths on the oscilloscope probe. Long ground leads can erroneously inject high frequency noise into the measured ripple. 2) For efficiency measurements, connect an ammeter in series with the input supply to measure the input current. Connect an electronic load to the output for output current. SETTING OUTPUT VOLTAGE: Table 1 shows a list of recommended component selections for common output voltages.
