The ADP1882-1.0-EVALZ is an evaluation board to test the ADP1882 switching controller at 1MHz switching frequency. The ADP1882 are versatile current mode, synchronous step-down controllers that provide superior transient response, optimal stability, and current-limit protection by using a constant on-time, pseudo-fixed frequency with a programmable current-limit, current-control scheme. In addition, these devices offer optimum performance at low duty cycles by using valley current mode control architecture. This allows the ADP1882 to drive all N-channel power stages to regulate output voltages as low as 0.8V. In addition an internally fixed soft start period is included to limit input in-rush current from the input supply during startup and to provide reverse current protection during soft start for a pre-charged output.

• Synchronous current-mode with constant on-time PWM buck controller
• Supports all N-channel Mosfet power stages
• No current-sense resistor required
• Resistor-programmable current-sense gain
• Thermal overload protection
• Short circuit protection
• Precision enable input
• Integrated bootstrap diode for high-side drive
• 140μA shutdown supply current
