Automotive Quad Output Regulator A4407KLPTR-T
The A4407 is an automotive power management IC that uses a 2.2MHz constant on-time (COT) buck pre-regulator to supply a 5V linear regulator, a 5V tracking/protected linear regulator, a 3.3V linear FET controller/driver, and a 1.2V/1.5V/1.8V linear FET controller/driver. The A4407 provides a pin to set the master reference for the 5V tracking regulator to either the 3.3V or the 5V output. The on-time of the buck is internally adjusted as a function of VIN to maintain the 2.2MHz switching frequency. Efficient operation is achieved by using the buck pre-regulator to drop the input voltage before supplying the linear regulators. Designed to supply CAN and microprocessor power supplies in high temperature environments, the A4407 is ideal for under hood applications. The switching regulator is designed to operate at a nominal switching frequency of 2.2MHz. The high switching frequency enables the customer to select low value inductors and ceramic capacitors while avoiding EMI in the AM frequency band. Protection features include: undervoltage lockout, pulse-bypulse current limit, LX short circuit protection, and thermal shutdown. In case of a shorted load all linear regulators feature foldback overcurrent protection. In addition, the V5P output is protected from a short-to-battery event. The A4407 features both a logic level and a high-voltage (current and voltage limited) enable input. The A4407 also features a power-on-reset (NPOR) output with adjustable delay for microprocessor control. The A4407 is supplied in a low profile (1.1 mm) 24-lead TSSOP package with exposed pad for enhanced thermal dissipation (suffix LP). The package is lead (Pb) free with 100% matte-tin leadframe plating.
