power mosfets for dc/dc conversion and li-ion battery protection pa272xut1a and pa273xut1a series defeating heat with a small package, these two series of power mosfets from nec electronics america handle dc/dc conversion and battery protection tasks. the devices low r ds(on) minimizes power dissipation, and an hvson package trims device thickness to just 1 millimeter (mm). this package enables part of the devices lead frame to connect directly to the circuit board for effcient heat dissipation. both series of devices are 4.5v gate-driven types, and both are particularly well suited for notebook pcs. the pa272xut1a series consists of n-channel mosfets that provide high-speed switching performance to handle synchronous rectifer applications for dc/dc converters. r ds(on) is as low as 2.5 m max at a v gs of 10v (i d = 17a). all of these devices have a v dss of 30v. designed to provide protection for battery applications, the pa273xut1a series prevents heat generation and explosions that may result from lithium-ion-battery over-current. this series consists of p-channel mosfets that have a v dss of C30v. r ds(on) for these devices is down to 2.6 m max at a v gs of C10v (i d = 22a). www.am.necel.com/powermanagement n- and p-channel mosfets hvson package key features > extremely low on-state resistance > thin, high-power hvson package > 4.5v gate-driven confguration applications > synchronous rectifers in dc/dc converters > notebook computers > servers applications nec electronics part number v dds (v) i d (dc) (a) r ds(on) typ/max ( mohm ) c iss ( p f) c rss ( p f) qg ( n c) v gs = 5v qg ( n c) @ 10v @ 4.5v low side in notebook pcs pa2722ut1a 30 29 2.6/3.3 3.4/4.6 6200 540 48 20 low side in notebook pcs pa2723ut1a 30 33 2.0/2.5 3.6/3.5 8610 700 67 23 dc/dc converters pa2724ut1a 30 29 2.7/3.3 3.5/5.0 4610 430 39 13 dc/dc converters pa2725ut1a 30 25 3.8/5.0 5.2/7.5 2800 260 24 7.5 dc/dc converters pa2726ut1a 30 20 5.7/7.0 7.7/11 1920 170 17 5.2 dc/dc converters pa2727ut1a 30 16 7.7/9.6 10/15 1260 110 11 3.3 pa272xut1a series 1.0mm max. 6.0mm max. 5.15mm max.
