7.5-100V 宽输入电压,100mA 恒定导通时间同步降压稳压器 8-WSON -40 to 125
The LM5019 is a 100-V, 100-mA synchronous step-down regulator with integrated high-side and low-side MOSFETs. The constant-on-time COT control scheme employed in the LM5019 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.
The LM5019 device is available in WSON-8 and SO PowerPAD-8 plastic packages.
