Key Features
- 7.6 A peak source/sink capability drives large power MOSFETs with gate charge up to 100 nC for fast switching
- Gated Schmitt-trigger input provides hysteresis for clean switching even with noisy PWM control signals
- Alternative pilot output enables direct monitoring of gate drive activity for protection or diagnostic circuits
- 6-pin SOT-23 package (S-PDSO-N6) minimizes PCB space in compact DC-DC converter modules
Applications
LM5134BSD/NOPB is designed for synchronous buck, boost, and LLC resonant converter topologies where a strong low-side gate driver is needed to minimize switching losses at frequencies above 100 kHz. The Schmitt-trigger input tolerance and 7.6 A peak drive current make it effective in motor drive half-bridge stages, UPS inverter circuits, and Class-D audio amplifier output stages operating at high switching frequencies.

Frequently Asked Questions
What peak gate drive current does LM5134BSD/NOPB supply, and what MOSFET gate charge range does that cover?
LM5134BSD/NOPB delivers 7.6 A peak current, which can fully charge a 100 nC gate in approximately 13 ns. This makes it suitable for driving medium to large power MOSFETs in 48 V DC-DC converters without a secondary boost stage in the gate drive path.
How does the Schmitt-trigger input of LM5134BSD/NOPB improve reliability in noisy switching environments?
The gated Schmitt-trigger input adds hysteresis to the switching threshold, typically 200 mV or more, preventing spurious toggling caused by ground bounce or high dV/dt noise on the PWM control line. This improves EMI performance and eliminates false turn-on events in converters switching at 200 kHz to 500 kHz.
In which converter topology would LM5134BSD/NOPB be paired with a high-side driver such as LM5101?
In a synchronous buck converter, LM5134BSD/NOPB would handle the low-side synchronous rectifier MOSFET while LM5101 or similar drives the high-side switch. The 7.6 A peak drive of LM5134BSD/NOPB matches well with high-side drivers in 12 V to 48 V point-of-load converters delivering 10 A to 30 A output current.
