The PM6640TR is a DC-DC switching regulator designed to convert input voltages in a wide range of market applications, including portable battery-operated equipment and distributed power systems. The device utilizes a peak current mode, fixed frequency control scheme to regulate output voltage. It provides highly efficient power conversion in a small package (only 5mmx5mm), which allows for easy integration into end products.

The PM6640TR operates from 2.7V to 28V input voltage range, with nominal input voltage of +5V. It includes an integrated power switch and a built-in soft-start function. It supports output voltages from 1V up to 20V, with operating frequency adjustable from 100kHz to 600kHz via external resistors. The PM6640TR is capable of delivering up to 1A of output current and has a programmable duty cycle control. It also features thermal shut-down protection for over-temperature events.

The PM6640TR application field covers a broad range of portable and distributed power systems. These systems include smart wearable devices, medical equipment, ZigBee/Bluetooth/Bluetooth Low Energy (BLE) gateways, and other applications. The PM6640TR is particularly suited for applications operating from battery sources, as it is extremely efficient and provides low power consumption.

The PM6640TR working principle is based on peak current mode control architecture, wherein the output voltage is controlled by a loop composed of an error amplifier, a reference voltage, a PWM comparator, a peak current-sense comparator and an output switch. When the input voltage is applied to the device, the current through the output switch is monitored, and compared to the reference voltage. If the current is higher than the reference voltage, the peak current detector control loop turns off the output switch, allowing the voltage to decrease. Conversely, if the current is lower than the reference voltage, the peak current detector turns on the output switch and the current through the output switch increases, increasing the output voltage.

The PM6640TR provides an efficient and stable regulation of a wide range of input and output voltages, with adjustable switching frequency. This makes it a suitable solution for powering a variety of portable and distributed power systems. The device is also exceptionally small and lightweight, making it suitable for inclusion in wearable and other small form factor products. Additionally, its low power consumption ensures prolonged operation of the powered device without compromising battery performance.
