The AP34063S8L-13 is a switching voltage regulator integrated circuit specifically designed for automotive applications, considered part of the PMIC – Voltage Regulators – DC/DC Switching Regulators group. The voltage regulator is housed in a 2 x 2 mm SO8 package and is rated for input voltage between 4.5 V and 40 V. Its production is operated by 20mΩ internal power MOSFETs that can support up to 1.5 A of continuous output current.

The main advantage of this regulator is its low noise feature. The AP34063S8L-13 operates at very low (around 40dB) noise level over the frequency range of 100 KiHz ~ 500 KiHz. Its x2 NR pin reduces the noise of the synchronous rectifier, improves power efficiency, and reduces output voltage ripples. Moreover, the AP34063S8L-13 integrated circuit includes several features that improve its design flexibility like its “spread spectrum and cycle skip that can be enabled/disabled”, its “internal soft-start” and, with respect to its output voltage, its “zero current limit with external resistor”.

Regarding its working principle, the dual-mode architecture of this circuit has two operational states: Discontinuous Conduction Mode (DCM) and Continuous Conduction Mode (CCM). In DCM, parts of the energy stored in the inductor L is released to the output capacitor, reducing the inductor current that eventually drops to zero and generating an output voltage spike. On the other hand, in CCM, the inductor current remains greater than zero and experiences a smooth, controlled decrease until it reaches the “gate driver off” state.

This device is ideal for power pockets applications on automotive diagnostics, car multimedia, HVAC air conditioning, car monitoring system, and car audio systems. Its Sync pin frequency range allows it to be part of solutions featuring low-cost controllers and other circuits with very low noise levels.

In conclusion, the AP34063s8L-13 belongs to the PMIC – Voltage Regulators – DC/DC Switching Regulators group. Its dual-mode architecture, low power losses and wide input range makes it a good choice for low noise solutions and power pockets applications.
