What are the key features of LM3370SDX-3416/NOPB?
- Dual synchronous step-down channels with dynamic voltage scaling (DVS) enable on-the-fly voltage transitions for processor core supply management
- PFM/PWM automatic mode switching optimizes efficiency at light loads while maintaining tight regulation at full load from a 2.7 V to 5.5 V input
- Adjustable output range of 1.4 V to 2.8 V in a compact 16-pin WSON package suits multi-core mobile SoC power supply designs
What is LM3370SDX-3416/NOPB used for?
The LM3370SDX-3416/NOPB is designed for mobile processor and DSP core supply rails where dynamic voltage scaling is required to reduce power during low-performance operating states. Its dual synchronous step-down topology efficiently powers two independent voltage domains from a single 3.6 V nominal Li-Ion cell in smartphones, tablets, and portable media players. The WSON package and PFM light-load mode extend battery life in always-on subsystems by minimizing switching losses at standby currents.

Frequently Asked Questions
How does dynamic voltage scaling in the LM3370SDX-3416/NOPB reduce processor power in a mobile SoC design?
Dynamic voltage scaling allows the host processor to command the LM3370SDX-3416/NOPB to shift the core supply from a high-performance level such as 1.8 V down to a low-power state of 1.4 V during idle or low-frequency operation, reducing dynamic power approximately quadratically with voltage. The converter transitions smoothly between the 1.4 V to 2.8 V adjustment range under firmware control, avoiding voltage overshoot or undershoot that could cause CPU faults.
What is the input voltage range of the LM3370SDX-3416/NOPB, and how does PFM mode extend Li-Ion battery life?
The LM3370SDX-3416/NOPB accepts input voltages from 2.7 V to 5.5 V, spanning the full discharge range of a single-cell Li-Ion battery from 4.2 V charged down to 2.7 V cutoff. In PFM (pulse frequency modulation) mode at light loads, the converter skips switching cycles and reduces gate drive losses, improving efficiency from typically 70% in PWM mode to above 85% at sub-10 mA load currents in standby.
How does the 16-pin WSON package of the LM3370SDX-3416/NOPB compare to a TSSOP in terms of PCB area for a dual-rail power supply?
The 16-pin WSON package occupies approximately 4 mm × 4 mm with a thermal pad, roughly 30% smaller in footprint than an equivalent 16-pin TSSOP at 5 mm × 4.4 mm. This space saving is significant in mobile and wearable designs where the dual-channel power supply must fit within 16 mm² of board area adjacent to the application processor.
