What are the key features of LM27342MY/NOPB?
- 2 A peak output current with 3 V to 20 V wide input range enables single-chip power regulation across automotive, industrial, and telecom supply rails
- Current-mode PWM control with adjustable output from 1 V to 18 V simplifies compensation and enables fast load transient response
- Compact SOT-23-10 package (3 mm × 3 mm) and frequency synchronization feature reduce EMI and simplify multi-rail power design
What is LM27342MY/NOPB used for?
LM27342MY/NOPB targets point-of-load DC-DC conversion in space-constrained boards powered from unregulated 5 V, 12 V, or 18 V rails. Its wide 3 V to 20 V input range makes it suitable for industrial sensor nodes, telecom line cards, and automotive infotainment sub-modules needing a stable 1 V to 18 V regulated output. The frequency synchronization input allows multiple regulators to be phase-staggered on a common clock, reducing input capacitor ripple in multi-channel power supply designs.

Frequently Asked Questions
Can LM27342MY/NOPB regulate down from a 12 V input to a 3.3 V output at 2 A for an industrial sensor board?
Yes. LM27342MY/NOPB accepts a 12 V input well within its 3 V to 20 V range and can regulate to a 3.3 V output at up to 2 A load current using external resistor dividers. The current-mode PWM architecture maintains output stability during load steps from 0 A to 2 A, while the adjustable mode allows the same feedback network to be tuned for any output between 1 V and 18 V without changing the IC.
How does the frequency synchronization feature of LM27342MY/NOPB reduce input capacitor stress in multi-rail designs?
LM27342MY/NOPB includes a frequency synchronization pin that locks its switching frequency to an external clock, typically between 500 kHz and 2 MHz. By phase-staggering two or more LM27342MY converters on a common board at 180° offsets, peak input current draw is spread over time, reducing RMS ripple current through shared input bulk capacitors by up to 50% and allowing the use of smaller, lower-cost capacitors.
For a compact automotive sub-module PCB, how much board area does the LM27342MY/NOPB SOT-23-10 package consume?
The SOT-23-10 package has a body measuring approximately 3 mm × 3 mm, occupying under 10 mm² of PCB footprint. Combined with small external passives (inductor, input and output capacitors), a complete 2 A LM27342MY/NOPB regulator circuit typically fits within 150 mm² — significantly smaller than a comparable discrete MOSFET plus controller solution, reducing cost and assembly complexity for automotive ECU and dashboard power rails.
