Design a Custom BoardThe AP3031 is an inductor-based DC/DC boost converter IC designed to drive white LED arrays in LCD backlighting applications. It features 1MHz constant-frequency PWM control, 1.4A switching current, and supports input voltages from 2.7V to 16V with up to 92% efficiency. Built-in protections include over-voltage detection, under-voltage lockout, cycle-by-cycle current limiting, soft-start, and thermal shutdown.
SOT-23-6 packages house precision regulators, voltage references, and level shifters with 0.95mm pin pitch—too fine for hand soldering and incompatible with breadboards. A breakout board provides through-hole headers for prototype work, eliminating soldering difficulty while enabling quick circuit iteration. Essential for developing with compact analog and power management ICs.
