3 Description

The TLVM365R15 and TLVM365R1 are 150-mA or

100-mA, 65-V input, synchronous step-down DC/DC

power modules that combine power MOSFETs,

integrated inductor, and boot capacitor in a compact

and easy-to-use 3.5-mm × 4.5-mm × 2-mm, 11-pin

QFN package. The small HotRod™ QFN package

technology enhances the thermal performance and

low EMI. The device features the ultra-low operating

IQ of 4 μA at no load (24-V to 3.3-V VOUT). The

TLVM365R15 and TLVM365R1 support fixed 3.3-V

and 5-V outputs, as well as adjustable output voltages

ranging from 1 V to 6 V. The devices only require

four external components for a 3.3-V and 5-V fixed

output design. The TLVM365R15 and TLVM365R1

are designed for excellent EMI performance and

space constraint applications.
