- Standard logic input interface allows direct PWM control from digital controllers without level shifting
- Compact 20-pin QFN package minimizes PCB footprint in dense power conversion boards
- Single-channel low-side architecture simplifies synchronous buck and boost converter gate drive
Applications
The UCD7230RGWR is used in synchronous DC/DC converters and digital power supplies where its 4 A peak gate drive current reduces MOSFET switching losses at frequencies above 100 kHz. It is well-suited for server and telecom power modules controlled by digital PWM controllers, providing strong low-side gate drive with standard logic compatibility. Industrial motor drives and point-of-load converters also benefit from its compact QFN packaging and robust output current capability.

Frequently Asked Questions
What peak gate drive current does UCD7230RGWR provide and how does it affect switching speed?
The UCD7230RGWR delivers a nominal 4 A peak output current for driving MOSFET gates. Higher peak drive reduces the gate charge time of power MOSFETs with Qg values of 50 nC to 200 nC, enabling faster turn-on and turn-off transitions at switching frequencies of 100 kHz to 1 MHz and reducing switching losses in converter efficiency budgets.
Can UCD7230RGWR be driven directly from a 3.3 V digital PWM controller output?
Yes, the UCD7230RGWR has standard input characteristics compatible with 3.3 V and 5 V logic signals from digital PWM controllers and DSPs. No additional level translator is needed, which simplifies the signal path between a digital power controller IC and the MOSFET gate driver in server power supply and telecom rectifier designs.
In which converter topologies is UCD7230RGWR most commonly used as a low-side driver?
The UCD7230RGWR is commonly deployed as the low-side switch driver in synchronous buck converters, synchronous boost converters, and totem-pole PFC stages. Its 4 A peak drive and low-side-only topology make it a dedicated lower-switch gate driver that pairs with a high-side bootstrap driver to complete the half-bridge stage in point-of-load modules.
How does the 20-pin QFN package of UCD7230RGWR benefit high-density power supply PCB designs?
The 20-pin QFN (S-PQCC-N20) package of UCD7230RGWR provides an exposed thermal pad for heat dissipation and a small body footprint of approximately 3 mm × 3 mm or 4 mm × 4 mm, allowing placement adjacent to the power MOSFET to minimize gate drive loop inductance and reduce voltage ringing at switch transitions above 500 kHz.
