Topology flexibility in a TSOT-23-5 footprint
The LT1615ES5#TRMPBF is a current-mode DC-DC converter that operates in either boost or SEPIC topology from a single 1V minimum input up to 15V maximum. The adjustable output can be set as high as 34V, making it suitable for generating intermediate rails or biasing supplies from low-voltage sources like single-cell alkaline or Li-Ion batteries. The internal 300mA switch handles the power stage; the actual output current depends on the input-to-output voltage ratio and topology. In a typical 3.3V-to-5V boost, the available output current is lower than the switch rating due to the duty cycle and inductor losses.
The supplier device package is TSOT-23-5, matching the package/case designation. It is not specified for automotive or extended industrial temperature environments. The single positive output is adjustable via an external resistor divider from a 1.23V reference. No synchronous rectifier is integrated, so an external Schottky diode is required in the boost or SEPIC configuration.
Lifecycle and compliance status
It is fully ROHS3 compliant, meeting EU Directive 2011/65/EU and its amendments. Available in Tape & Reel (TR) or Cut Tape (CT) packaging options, the TR suffix indicates full reel quantities suitable for automated pick-and-place assembly. Pricing and lead time are confirmed at quote against your BOM quantity.
