LTM8002 40V , 2.5A Silent Switcher IN Module Regulator FEATURES DESCRIPTION n Complete Step-Down Switch Mode Power Supply The LTM 8002 is a 40V , 2.5A step-down Module IN n Low Noise Silent Switcher Architecture (power module) regulator. Included in the package are n Wide Input Voltage Range: 3.4V to 40V the switching controller, power switches, inductor, and n Wide Output Voltage Range: 0.97V to 18V all support components. Operating over an input voltage n Wide Temperature Range: 40C to 150C (H-Grade) range of 3.4V to 40V, the LTM8002 supports an output n 2.8A Continuous for 5V , 12V , 2MHz at 105C voltage range of 0.97V to 18V and a switching frequency OUT IN (H-Grade) range of 200kHz to 3MHz, each set by a single resistor. n 3.5A Peak Only the input and output filter capacitors are needed to n FMEA Compliant Pinout finish the design. Output Stays at or Below Regulation Voltage During The low profile package enables utilization of unused Adjacent Pin Short or if a Pin Is Left Floating space on the bottom of PC boards for high density point of n Selectable Switching Frequency: 200kHz to 3MHz load regulation. The LTM8002 is packaged in a thermally n External Synchronization enhanced, compact over-molded ball grid array (BGA) n Low Quiescent Current: 25A (5V ) OUT package suitable for automated assembly by standard n Programmable Soft-Start surface mount equipment. The LTM8002 is available with n Tiny, Low Profile 6.25mm 6.25mm 2.22mm SnPb or RoHS compliant terminal finish.
