The LM5175 operates over a wide input voltage range of 3.
5 V to 42 V (60 V maximum) to support a variety of applications.
The LM5175 employs current-mode control both in buck and boost modes of operation for superior load and line regulation.
The switching frequency is programmed by an external resistor and can be synchronized to an external clock signal.
The device also features a programmable soft-start function and offers protection features including cycle-by-cycle current limiting, input undervoltage lockout (UVLO), output overvoltage protection (OVP), and thermal shutdown.
In addition, the LM5175 features selectable Continuous Conduction Mode (CCM) or Discontinuous Conduction Mode (DCM) operation, optional average input or output current limiting, optional spread spectrum to reduce peak EMI, and optional hiccup mode protection in sustained overload conditions.
