The ISL6535IRZ is a feature-rich, integrated pulse-width modulation (PWM) controller that is ideal for powering load applications in a range of electronic devices. The device integrates efficient power control functions into a small and space-saving, 6mm × 5mm surface mountable package. Designed to power many types of load applications primarily from a single or multiple battery sources, the ISL6535IRZ is a versatile and cost-effective solution for power system design.

The ISL6535IRZ is designed to fit many different applications, including portable medical and dental equipment, industrial robots and automation systems, consumer appliances, laptops and consumer electronics. The device supports a wide input voltage range, from 3.1V to 16V, and features low quiescent supply current, adjustable output over-voltage protection, internal soft start and selectable synchronous or asynchronous rectification.

When operating in asynchronous rectification mode, the ISL6535IRZ can reach peak efficiency of up to 95%, enabling a compact solution for demanding load applications. The unique inductor-less topology allows for the controller to provide high voltage output rails from the same power supply, making it ideally suited for broadcast audio and consumer audio applications.

The device supports a full range of output power frequency and voltage control. The adjustable switching frequency enables high-efficiency operation over wide line, load and temperature ranges. An automatic voltage scaling feature enables the output voltage to be changed without compromising the switching frequency. In addition, the controller features fault protection circuitry, including under-voltage lockout and over-temperature protection.

The ISL6535IRZ has a pulse-by-pulse current limit protection, which ensures the safe operation of the system even in abnormal conditions. The device also features an on/off logic setting, which allows the controller to be integrated into existing systems with minimal circuit redesign. The device also features programmable loop compensation, which allows the device to accurately control the output voltage of the system.

In addition to its versatile feature set, the ISL6535IRZ is also easy to use and cost-effective. The device requires minimal external components and can be quickly deployed in a variety of applications. Furthermore, the small surface area of the device allows for high density system integration. The ISL6535IRZ is an ideal solution for applications requiring the highest level of power density, low noise operation and excellent EMI performance.
