Typical Application
Description
The LTM®8027 is a complete 4A, DC/DC step-down power supply. Included in the package are the switching controller, power switches, inductor and all support components. Operating over an input voltage range of 4.5V to 60V (7.5V minimum voltage to start), the LTM8027 supports output voltages up to 24V, and a switching frequency range of 100kHz to 500kHz, each set by a single resistor. Only the bulk input and output filter capacitors are needed to finish the design.
The low profile package (4.32mm) enables utilization of unused space on the bottom of PC boards for high density point of load regulation. A built-in soft-start timer is adjustable with a small capacitor.
The LTM8027 is packaged in a compact (15mm × 15mm × 4.32mm) over-molded land grid array (LGA) and (15mm × 15mm × 4.92mm) BGA package suitable for automated assembly by standard surface mount equipment. The LTM8027 is available with SnPb (BGA) or RoHS compliant terminal finish.
