Texas Instruments LM25017/8/9 48V Step-Down Regulators

Texas Instruments LM25017 / LM25018 / LM25019 are 48V synchronous step-down regulators with integrated high side and low side MOSFETs. The constant-on-time (COT) control scheme employed in the TI LM25017 / LM25018 / LM25019 requires no loop compensation, provides excellent transient response, and enables very low step-down ratios. The on-time varies inversely with the input voltage resulting in nearly constant frequency over the input voltage range. A high voltage startup regulator provides bias power for internal operation of the IC and for integrated gate drivers. A peak current limit circuit protects against overload conditions. The undervoltage lockout (UVLO) circuit allows the input undervoltage threshold and hysteresis to be independently programmed. Other protection features include thermal shutdown and bias supply undervoltage lockout (VCC UVLO).
