Frequently Asked Questions
What is the input voltage range of the LM3354MM-1.8?
The LM3354MM-1.8 accepts an input voltage range of 2.5V to 5.5V, with a nominal operating point of 3.5V. This makes it compatible with single-cell Li-Ion batteries (2.7V–4.2V) as well as regulated 3.3V and 5V supply rails in embedded systems.
What output voltage does the LM3354MM-1.8 provide?
The LM3354MM-1.8 provides a fixed 1.8V regulated output voltage. The maximum output is specified at 1.872V, ensuring tight regulation for powering 1.8V logic, memory interfaces, and low-voltage processors in portable designs.
What package does the LM3354MM-1.8 come in, and why does it matter?
The LM3354MM-1.8 is housed in a 10-pin MSOP (S-PDSO-G10) small outline package. This compact footprint is ideal for space-constrained PCBs in handheld and wearable applications. The charge pump topology also eliminates the need for an external inductor, further reducing total solution size.
What control method does the LM3354MM-1.8 use?
The LM3354MM-1.8 uses voltage-mode pulse width modulation (PWM) control. This technique provides stable, low-ripple output regulation by continuously adjusting the duty cycle in response to output voltage variations, making it suitable for noise-sensitive analog and mixed-signal circuits.
What are typical applications for the LM3354MM-1.8?
Typical applications include portable consumer electronics (smartphones, cameras, handheld gaming), IoT sensor nodes, wireless communication modules, and low-power embedded systems that require a compact, inductor-free 1.8V regulated supply from a Li-Ion or alkaline battery source.
