Frequently Asked Questions
What topology best exploits the low RDS(on) of RFM12U7X(TE12L,Q) in a mobile power supply?
Synchronous buck DC-DC converters operating at 1 MHz to 3 MHz switching frequency benefit most from RFM12U7X(TE12L,Q)'s low RDS(on) because the dominant power loss is conduction loss at duty cycles above 50%, and a low-resistance N-channel MOSFET in the low-side switch position directly reduces I²R heating across the full 1 A to 5 A output current range.
How does the PW-X package of RFM12U7X(TE12L,Q) compare to SOT-23 in terms of board space?
The PW-X package used by RFM12U7X(TE12L,Q) is a compact ultra-small surface-mount package with a footprint smaller than 2 mm × 2 mm, making it comparable to or smaller than SOT-23, which occupies approximately 3 mm × 1.75 mm. This allows higher switch density on power management boards where 5 to 10 MOSFET cells must fit in a tight power stage layout.
For a 3.3 V to 5 V Li-ion battery charging circuit, is RFM12U7X(TE12L,Q) a viable low-side switch?
RFM12U7X(TE12L,Q) is a viable low-side N-channel switch for a 3.3 V to 5 V Li-ion charger path when the gate driver can supply a VGS of at least 4.5 V, ensuring the device operates fully enhanced with minimum RDS(on). Its fast turn-on and turn-off transitions at switching frequencies of 1 MHz or higher also help keep the inductor size below 2.2 µH in a typical synchronous charging topology.
