STEVAL-ISA101V1:2 A DC step-down switching regulator with 4 V/36 V input voltage range based on the L5973D
The STEVAL-ISA101V1 demonstration board is based on the L5973D, a step-down monolithic switching regulator with 2 A DC (2.5 A switch peak current) current capability over the output voltage range (1.235 V to 36 V).
The operating input voltage ranges from 4 V to 36 V. The device is based on BCD5 technology. The embedded power element is a P-channel D-MOS transistor so the driving stage does not require any bootstrap capacitor and the duty cycle can range up to 100%.
An internal oscillator fixes the switching frequency at 250 kHz. A synchronization pin is available when a higher switching frequency (up to 700 kHz) is required.
Pulse-by-pulse current protection and a frequency foldback feature always guarantee an effective short-circuit protection. Other features include voltage feed-forward, protection against feedback disconnection, inhibit and thermal shutdown.
