Overview
The L4972A is a 2A monolithic step-down switching regulator with a 5.1V to 40V output voltage range and 0 to 90% duty cycle range.
Key Features
Internal feed-forward line regulation, precise 5.1V * 2% on-chip reference, reset and power fail functions, input/output sync pin, under-voltage lockout with hysteresis turn-on, PWM latch for single pulse per period, very high efficiency, and thermal shutdown.
Continuous mode operation with switching frequencies up to 200kHz, making it suitable for microprocessor-based systems.
