DC-DC преобразователи интегральные LM34910CSD/NOPB

Импульсный понижающий DC-DC стабилизатор , регулируемый, 8В-50В (Vin), 2.5В-45В, 1.25А, WSON-10

The LM34910CSD/NOPB is a step-down Switching Regulator features all of the functions needed to implement an efficient, buck bias regulator capable of supplying 1.25A to the load. This buck regulator contains a 55V N-channel buck switch. The hysteretic regulation scheme requires no loop compensation, results in fast load transient response and simplifies circuit implementation. The operating frequency remains constant with line and load variations due to the inverse relationship between the input voltage and the on-time. The current limit detection is set at 1.25A. Additional features include VCC undervoltage lockout, thermal shutdown, gate drive undervoltage lockout and maximum duty cycle limiter.
