Product Overview
PTH05050WAH from TI is a 6A non-isolated DC-DC power module with 4.5-5.5V input and 0.8-3.6V adjustable output. SIP through-hole package. Integrated inductor. >95% efficiency. Pre-bias start-up.
Working Principle
Complete DC-DC converter module integrating PWM controller, MOSFETs, and inductor. Only external capacitors needed. Auto-tracking and sequencing. Margin up/down pins for system test. Pre-bias start-up protects loads with existing voltage.
