LT3467ES6#PBF

LT3467 is a compact integrated boost DC/DC converter with built-in Schottky diode. E stands for extended industrial temperature grade, S6 denotes 6-lead TSOT-23 surface mount package. #PBF means lead-free tape-and-reel packaging for automated large-scale SMT assembly.

This high-efficiency step-up switching regulator adopts fixed frequency current mode control topology, designed for battery-powered portable devices requiring elevated output voltage. The input supply range covers 1.8 V to 12 V, which fully fits single-cell lithium batteries, multi-cell alkaline batteries and small regulated low voltage power sources.

Internal power switch and integrated catch diode simplify peripheral circuit layout drastically. The switching frequency is fixed at 1.3 MHz, allowing the use of tiny inductors and ceramic capacitors to shrink the overall power solution footprint. Output voltage can be flexibly set via an external resistive divider, supporting adjustable positive output voltages higher than the input level.

Peak switch current limit is internally fixed to prevent overload damage. Complete protection circuits are embedded, including cycle-by-cycle current limiting, thermal shutdown protection and under-voltage lockout. When the device is pulled into shutdown mode, quiescent current drops below 1 μA to minimize battery drain during long standby periods.

High conversion efficiency is maintained across light and medium load conditions, effectively prolonging the service life of rechargeable batteries. The compact control scheme delivers fast transient response to sudden load changes and stable output voltage under varying input voltage conditions.

Encapsulated in miniature 6-pin TSOT-23 plastic surface mount package with ultra-small body size, perfectly suited for highly compact wearable electronics and handheld devices with limited PCB space. Moisture Sensitivity Level is MSL1, no time limitation exists for reflow soldering after vacuum packaging is opened. Continuous tape reel feeding is fully compatible with automatic pick-and-place machinery for mass electronic manufacturing.

Operating temperature range spans -40 °C to +85 °C, supporting steady continuous operation in portable medical gadgets, handheld measuring tools, wearable electronic equipment and remote wireless sensor nodes under fluctuating ambient temperatures. Fabricated with lead-free manufacturing processes, the component complies with global RoHS environmental directives. On-chip integration of the rectifier diode cuts down external component count and greatly simplifies small boost power supply design.
