描述

TPSM842xx 電源模塊是一種簡(jiǎn)單易用的集成式電源解決方案，它將 1.5A 直流/直流轉(zhuǎn)換器與功率MOSFET、電感器和無(wú)源器件整合在一個(gè) 3 引腳的穿孔插入式封裝內(nèi)。這套完備的電源解決方案只需要增加輸入和輸出電容器，省去了設(shè)計(jì)過(guò)程中的環(huán)路補(bǔ)償和磁性元件選擇。借助標(biāo)準(zhǔn) TO-220 引腳，可在這一業(yè)界標(biāo)準(zhǔn)封裝中更換為明顯改善的線性穩(wěn)壓器。TPSM842xx 器件提供更高的效率而無(wú)需散熱片。

The TPSM842xx power module is an easy-to-use integrated power solution that combines a1.5-A DC/DC converter with power MOSFETs, an inductor, and passives into a 3-pin, through-holepackage. This total power solution requires adding only input and output capacitors and eliminatesthe loop compensation and magnetics part selection from the design process. The standard TO-220 pin-out allows a much improved replacement of linear regulatorspackaged in this industry standard footprint. The TPSM842xx devices provide much higher efficiencywithout the need of a heatsink.特性 Complete Integrated Power Solution3-PinTO-220 FootprintEfficiencies up to 95%Fixed Output Voltage Options:3.3 V, 5 V, and 12 V400-kHz SwitchingFrequencyAdvanced Eco-mode?
