Nkọwa
TPS61088 bụ njupụta ike dị elu, ihe ngbanwe nkwalite mmekọrịta zuru oke na mgba ọkụ 11-mΩ yana mgba ọkụ 13-mΩ na-agbanwe iji nye arụmọrụ dị elu na obere nha nha na sistemụ mkpanaka.TPS61088 nwere oke ntinye voltaji sitere na 2.7 V ruo 12 V iji kwado ngwa nwere otu cell ma ọ bụ batrị lithium cell abụọ.Ngwaọrụ nwere ikike ngbanwe nke 10-A ma nwee ike ịnye voltaji mmepụta ruo 12.6 V. TPS61088 na-eji ihe na-agbanwe agbanwe oge niile na-apụ n'oge kacha elu ugbu a akara topology iji mezie voltaji mmepụta.N'ọnọdụ dị oke oke ma dị arọ, TPS61088 na-arụ ọrụ na ọnọdụ pulse width modulation (PWM).N'ọnọdụ ibu ọkụ, ngwaọrụ ahụ nwere ụdị ọrụ abụọ nke MODE pin họpụtara.
Otu bụ ọnọdụ pulsefrequency modulation (PFM) iji melite arụmọrụ yana nke ọzọ a na-amanye ọnọdụ PWM iji zere nsogbu ngwa kpatara site na obere ngbanwe ugboro.Ugboro ngbanwe na ọnọdụ PWM bụ mgbanwe, sitere na 200 kHz ruo 2.2 MHz site na ihe mgbochi mpụga.TPS61088 na-arụkwa ọrụ mmalite dị nro nke nwere ike ime mmemme yana ọrụ ngbanwe kacha elu ugbu a.Tụkwasị na nke ahụ, ngwaọrụ ahụ na-enye 13.2-V mmepụta ihe nchebe overvoltage, nchebe n'ofe okirikiri, na mkpuchi mkpuchi ọkụ.TPS61088 dị na ngwugwu 4.50-mm × 3.50-mm 20-pin VQFN.
