What are the key features of LM3242TME/NOPB?
- Voltage-mode PWM control with adjustable output from 0.4 V to 3.6 V, enabling precise rail tuning for low-voltage processor and memory supplies
- 2.7 V to 5.5 V input range covering single-cell Li-Ion batteries and USB 5 V bus, ideal for mobile and wearable power stages
- Ultra-compact 9-ball BGA package minimizing PCB area for dense smartphone, tablet, and IoT module power management layouts
What is LM3242TME/NOPB used for?
The LM3242TME/NOPB is designed for smartphone, tablet, and wearable device power management where a compact step-down converter must deliver stable sub-1 V processor core or memory supply rails from a Li-Ion battery. Its 0.4 V minimum output and 600 mA current capability make it suitable for powering application processor cores, LPDDR memory, and AMOLED display driver subsystems. IoT modules and portable medical sensors also use this regulator to efficiently step down a 5 V USB input or 3.7 V battery to 1.0 V or 1.8 V supply rails with minimal quiescent current.

Frequently Asked Questions
What input and output voltage ranges does LM3242TME/NOPB support in a single-cell Li-Ion battery design?
LM3242TME/NOPB accepts input voltages from 2.7 V to 5.5 V, which covers a single-cell Li-Ion battery discharge range of 3.0 V to 4.2 V and a USB 5 V bus. The output is adjustable from 0.4 V to 3.6 V, allowing designers to power application processor cores at 0.9 V or memory interfaces at 1.8 V from the same battery rail.
How does the 9-ball BGA package of LM3242TME/NOPB compare to SOT-23 alternatives for dense mobile PCB designs?
The 9-ball BGA package of LM3242TME/NOPB measures approximately 1.5 mm × 1.5 mm with a 0.5 mm ball pitch, occupying roughly 2.25 mm² of PCB area. This is 60% to 70% smaller than a 6-pin SOT-23 footprint, enabling finer component placement in smartphone motherboards and compact IoT modules where every square millimeter is critical.
What control method does LM3242TME/NOPB use, and how does it affect output ripple at 600 mA load?
LM3242TME/NOPB uses voltage-mode PWM control, which provides deterministic switching frequency and easy external compensation. At 600 mA full load, the output voltage ripple is typically below 10 mV with a 4.7 µH inductor and 10 µF output capacitor, meeting the tight ripple requirements of LPDDR memory and RF front-end supply rails in mobile devices.
Can LM3242TME/NOPB replace a fixed-output LDO regulator for powering a 1.2 V DSP core from a 3.3 V rail?
LM3242TME/NOPB is an excellent step-down alternative to a 1.2 V LDO in this scenario. While an LDO dissipates (3.3 V − 1.2 V) × 600 mA = 1.26 W as heat, the LM3242TME/NOPB's PWM switching efficiency of 85% to 90% reduces power dissipation to under 200 mW, significantly lowering junction temperature and extending battery life in portable DSP designs.
