The LMZ14203 SIMPLE SWITCHER POWER MODULE IS AN EASY-TO-USE STEP-DOWN DC-TO-DC SOLUTION CAPABLE OF DRIVING LOADS UP TO 3A WITH EXCELLENT POWER CONVERSION EFFICIENCY, LINE AND LOAD REGULATION, AND OUTPUT ACCURACY. LMZ14203 is an innovative solution that enhances thermal performance and allows manual or machine welding.
The LMZ14203 accepts input voltage rails between 6V and 42V and provides adjustable and highly accurate output voltages down to 0.8V. The LMZ14203 requires only three external resistors and four external capacitors to complete the power solution. The LMZ14203 is a safe and reliable, powerful design with the following protection features: thermal shutdown, input undervoltage lockout, output overvoltage protection, short-circuit protection, output current limiting, and allows prebiased output start-up. 单个电阻器调节开关频率高达1 MHz。
