♠ TPS61193 Ọkwọ ụgbọ ala atọ na-arụ ọrụ dị elu
TPS61193 bụ onye na-arụ ọrụ dị elu, dị ala-EMI, onye ọkwọ ụgbọ ala LED dị mfe iji mee mgbanwe iji kwado ọtụtụ ngwa. Ọ nwere sinks atọ dị elu dị ugbu a nke nwere ike jikọta maka ikike dị elu ugbu a.
TPS61193 nwere DC-DC agbakwunyere na-akwado ma nkwalite yana ọrụ SEPIC. Onye ntụgharị ahụ nwere njikwa voltaji mmepụta ihe na-agbanwe agbanwe dabere na voltaji isi ụlọ nke LED dị ugbu a. Njirimara a na-ebelata oriri ike site n'ịgbanwe voltaji ka ọ bụrụ ọkwa kachasị ala na ọnọdụ niile. Maka njikwa EMI, ihe ngbanwe DC-DC na-akwado ịgbasa ụdịdị dị iche iche maka ịgbanye ugboro ole yana mmekọrịta mpụta nwere pin raara onwe ya nye.
TPS61193 nwere oke ntinye voltaji sitere na 4.5 V ruo 40 V maka nkwado siri ike nke ụdị ngwa dị iche iche. TPS61193 na-ejikọta ọtụtụ njirimara nchọpụta mmejọ. Ngwaọrụ na-akwado oke nchapụta nchapụta PWM nke 10 000:1 maka ntinye PWM ugboro 100-Hz.
