LM5008AMM General Description

Description for the LM5008AThe LM5008A DC/DC converter is a functional variant of the LM5008 COT Buck SwitchingRegulator. The functional differences of the LM5008A are: the minimum input operating voltage is 6V, the on-time equation is slightly different, and the requirement for a minimum load current isremoved.The LM5008A 350-mA step-down switching regulator features all of the functions requiredto implement a low-cost and efficient buck regulator. This high-voltage converter has an integrated100-V N-channel buck switch and operates over an input voltage range of 6 V to 95 V. The device iseasy to implement and is provided in 8-pin VSSOP and the thermally enhanced 8-pin WSON packages.The converter uses PWM control scheme with an on-time inversely proportional toVIN. This feature allows the operating frequency to remain relativelyconstant. The control scheme requires no loop compensation. An intelligent current limit isimplemented with forced off-time, which is inversely proportional to VOUT.This scheme ensures short-circuit control while providing minimum foldback. Other features include:thermal shutdown, VCC undervoltage lockout, gate drive undervoltage lockout,maximum duty cycle limiter, and a pre-charge switch.
