Overview

The LMZ23605 demo board is designed to be an easy-to-use platform to evaluate the full capabilities of this family of SIMPLE SWITCHER® power modules. The PCB construction has excellent thermal performance and includes extra locations for optional components that may not be required in the end application.

The LMZ23605 can accept an input voltage rail between 6V and 36V. The devices can deliver an adjustable and highly accurate output voltage as low as 0.8V and as high as 6V. The control architecture is constant frequency PWM with emulated current mode sensing. The control loop operates well with low ESR output capacitors such as ceramics or specialty polymer. The precision enable input allows for programmable UVLO on the input supply or flexibility in sequencing. The external soft-start capacitor facilitates controlled output rise time at startup. The module family is a reliable and robust solution with cycle-by-cycle valley current limit to protect for over current or short-circuit faults. Additionally there is thermal shutdown protection, and they will start up into a pre-biased output. The free-running switching frequency is 812 kHz (typ) and a 650 kHz to 950 kHz synchronization range is supported.
