What are the key features of LM3152MH-3.3/NOPB">?
- Fixed 3.3 V output synchronous buck regulator delivering up to 1.5 A with high conversion efficiency above 90%
- Wide input voltage range supporting conversion from 5 V, 12 V, or unregulated adapter rails down to a stable 3.3 V output
- 14-pin HTSSOP thermal package with exposed pad for improved heat dissipation in compact, high-current PCB designs
What is LM3152MH-3.3/NOPB"> used for?
LM3152MH-3.3/NOPB is suited for point-of-load 3.3 V power rails in embedded processors, FPGAs, and communication interface boards where efficiency and compact size are priorities. Its synchronous rectification topology reduces external diode losses and lowers heat generation, enabling reliable continuous operation at 1.5 A without bulky heatsinks. The HTSSOP package with exposed thermal pad facilitates heat transfer directly through the PCB, making it practical for thermally constrained designs such as industrial gateways and network switches.

Frequently Asked Questions
What continuous output current can LM3152MH-3.3/NOPB supply, and is 1.5 A enough for a mid-range FPGA core rail?
LM3152MH-3.3/NOPB provides up to 1.5 A continuous output current at 3.3 V, which covers the I/O power budget of many mid-range FPGAs such as Xilinx Artix-7 series. For larger FPGAs consuming more than 1.5 A at 3.3 V, multiple phases or a higher-current regulator would be required instead.
How does the synchronous buck topology of LM3152MH-3.3/NOPB improve efficiency compared to a non-synchronous converter at light load?
The synchronous rectifier replaces the external Schottky diode with an internal low-resistance NMOS switch, reducing rectifier forward-drop losses from approximately 0.4 V to under 0.05 V at 1 A. This raises conversion efficiency by 5% to 10% across the 100 mA to 1.5 A load range, reducing both heat dissipation and battery drain in portable equipment.
For a design converting a 12 V adapter rail to 3.3 V, what inductor and output capacitor values are typically recommended for LM3152MH-3.3/NOPB?
At 12 V input switching typically between 300 kHz and 600 kHz, a 4.7 µH to 10 µH inductor paired with a 22 µF to 47 µF low-ESR ceramic output capacitor is recommended for LM3152MH-3.3/NOPB. This combination keeps output voltage ripple below 30 mV peak-to-peak while maintaining stable transient response under 1.5 A step loads.
