Introduction

AI Translation

The ACT4752 is a programmable DC-to-DC buck converter with bias supply rails. This synchronous step-down voltage regulator supports a wide input voltage of 4.5 V to 40 V and integrates both the high side and low side MOSFETS. These 50mΩ RDSON transistors enable high efficiency by reducing power losses. The ACT4752 main buck converter can be dynamically programmed to an output voltage between 3 V and 24 V in 12.5 mV steps via the I²C or analog feedback. Also, it can dynamically program output current between 0 A to 4 A in 256 steps via the I²C in a constant-current (CC) operation mode. The main-buck operates in a proprietary current mode control that supports external clock syncing for switching frequencies between 450 kHz and 2.25 MHz. The ACT4752 is a perfect solution for USB Power Delivery 3.0 Programmable Power Supply (PD 3.0 PPS) charging applications. The ACT4752 integrates a 5 V / 350 mA mini-buck converter and a 20 mA AUX LDO to simplify application system designs. These rails can power up USB PD controllers and the 1.5W VCONN line in active USB-C cables. The ACT4752 is available in a 32-pin 5mm x 5mm QFN package with a power optimized footprint and exposed pad for improved thermal performance.
