Flexible digital power management solution features built-in autocompensation to reduce design times
The ZL8101 is an adaptive digital DC/DC PWM controller with auto compensation that provides a single phase solution with output currents up to 50 A. Designed to work with an external driver and with DrMOS solutions, it can be used in parallel for current sharing between multiple ZL8101 devices. It also can be deployed as a flexible building block for 12 V and 5 V down conversion where size, efficiency and monitoring are critical. The ZL8101 uses a dedicated, optimized, state machine for generating precise PWM pulses and a proprietary MCU for set-up and optimization.
By automatically compensating the power supply, designers using the ZL8101 can save weeks of design time and significantly improve reliability in a wide range of applications by relieving designers of the need for special tools, knowledge or experience to optimize performance. The device is ideal for wired and wireless systems, data communications, and power supply applications.
The ZL8101 is designed to work with drivers like the ZL1505 or ISL6611A phase doubler and features a PMBus interface that allows real-time monitoring of current, voltage and temperature. The PMBus interface guarantees full control over power supply operation and configuration. Most of the device’s operating features can be configured by simple pin-strap/resistor selection or through the SMBus serial interface.
Availability and Pricing
The ZL8101 is available now in QFN-32 packages, with prices starting at $3.10 each in 1,000-unit quantities.
