The low-side power MOSFET is integrated in the device, minimizing the total number of external components. Unique technology and high 0.9A current limit allow KTD257M to drive up to 39V output (10 LEDs in series). Alternatively, KTD257M can deliver 160mA total current with 3 series LEDs per string. It can also maximize the current capability while achieving high conversion efficiency. The optimized 900kHz switching frequency results in small external component size. The driver allows wide range of PWM dimming frequency through EN pin. Various protection features are built into the KTD257M, including cycle-by-cycle input current limit protection, LED open-circuit (output over voltage) protection and thermal shutdown protection. The leakage current in shutdown mode is less than 1\u03bcA.<\/p>\n<p>The KTD257M is available in a RoHS and Green compliant 6-lead TSOT23 package.<\/p>\n\t    <a href=\"https:\/\/pinakinnsoft.com\/kinetic\/wp-content\/uploads\/2026\/06\/KTD257_typ_app_dia.jpg\" class=\"gallery-image\" data-elementor-open-lightbox=\"yes\"\n   data-elementor-lightbox-slideshow=\"0\">\n\t\t\t<img decoding=\"async\" src=\"https:\/\/pinakinnsoft.com\/kinetic\/wp-content\/uploads\/2026\/06\/KTD257_typ_app_dia.jpg\" alt=\"\" \/>\n\t\t<\/a>\n\t\t    <a href=\"https:\/\/pinakinnsoft.com\/kinetic\/wp-content\/uploads\/2026\/06\/TSOT23-6_KTD257M_HD_3D.png\" class=\"gallery-image\" data-elementor-open-lightbox=\"yes\"\n   data-elementor-lightbox-slideshow=\"0\">\n\t\t\t<img decoding=\"async\" src=\"https:\/\/pinakinnsoft.com\/kinetic\/wp-content\/uploads\/2026\/06\/TSOT23-6_KTD257M_HD_3D.png\" alt=\"\" \/>\n\t\t<\/a>\n\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t\t<div id=\"tab-19099149202\" class=\"tab-pane fade \">\n\t\t\t\t\t\t\t<ul>\n<li>Wide output range: up to 10 series LEDs<\/li>\n<li>Integrated 40V high current switch (0.9A limit)<\/li>\n<li>VIN: 2.7V to 5.5V<\/li>\n<li>High efficiency PWM converter (up to 90%)<\/li>\n<li>Low 200mV feedback voltage<\/li>\n<li>LED open-circuit (OVP) protection\n<ul>\n<li>KTD257M: 39V<\/li>\n<\/ul>\n<\/li>\n<li>High switching frequency\n<ul>\n<li>KTD257M: 900kHz<\/li>\n<\/ul>\n<\/li>\n<li>PWM dimming frequency: 100Hz~200kHz<\/li>\n<li>Simple, small solution size<\/li>\n<li>Integrated Softstart<\/li>\n<li>&lt; 1 \u03bcA shutdown current<\/li>\n<li>Small TSOT23-6 Package<\/li>\n<li>RoHS and Green compliant<\/li>\n<li>-40\u00b0C to +85\u00b0C Temperature Range<\/li>\n<\/ul>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t\t<div id=\"tab-19099149203\" class=\"tab-pane fade \">\n\t\t\t\t\t\t\t<ul>\n<li>LED backlighting<\/li>\n<li>Mobile Phones<\/li>\n<li>Handheld Devices<\/li>\n<li>Digital Photo Frames<\/li>\n<li>Automotive Navigation<\/li>\n<\/ul>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t\t<div id=\"tab-19099149204\" class=\"tab-pane fade \">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<table class=\"tbl-product__table\">\n                                <thead>\n\t\t\t\t\t\t\t\t\t<tr>\n\t\t\t\t\t\t\t\t\t\t<td><strong>Package<\/strong><\/td>\n\t\t\t\t\t\t\t\t\t\t<td><strong>Dimensions<\/strong><\/td>\n\t\t\t\t\t\t\t\t\t\t<td><strong>Package Code<\/strong><\/td>\n\t\t\t\t\t\t\t\t\t<\/tr>\n                                 <\/thead>   \n                                 <tbody>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<tr>\n\t\t\t\t\t\t\t\t\t\t\t<td>TSOT23-6<\/td>\n\t\t\t\t\t\t\t\t\t\t\t<td>2.90mm x 2.80mm x 0.85mm<\/td>\n\t\t\t\t\t\t\t\t\t\t\t<td>HD<\/td>\n\t\t\t\t\t\t\t\t\t\t<\/tr>\n\t\t\t\t\t\t\t\t\t                                    <\/tbody>\n\t\t\t\t\t\t\t\t<\/table>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t\t<div id=\"tab-19099149205\" class=\"tab-pane fade \">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<table class=\"tbl-product__table\">\n                    <thead>\n\t\t\t\t\t\t<tr>\n\t\t\t\t\t\t\t<th>Purchase Options<\/th>\n\t\t\t\t\t\t<\/tr>\n                        <\/thead>\n                        <tbody>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\n\t\t\t\t\t\t\t\t<tr>\n\t\t\t\t\t\t\t\t\t<td><a class=\"icon-digikey\" href=\"https:\/\/www.digikey.com\/en\/products\/detail\/kinetic-technologies\/ktd257mehd-tr\/22311201\" target=\"_blank\">Buy from Digi-Key<\/a><\/td>\n\t\t\t\t\t\t\t\t<\/tr>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\n\t\t\t\t\t\t\t\t<tr>\n\t\t\t\t\t\t\t\t\t<td><a class=\"icon-mouser\" href=\"https:\/\/www.mouser.com\/ProductDetail\/Kinetic-Technologies\/KTD257MEHD-TR?qs=dbcCsuKDzFWN2hR28FCxgA%3D%3D\" target=\"_blank\">Buy from Mouser<\/a><\/td>\n\t\t\t\t\t\t\t\t<\/tr>\n\t\t\t\t\t\t\t\t\t\t\t\t\t                        <\/tbody>\n\t\t\t\t\t<\/table>\n\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Description Features Applications Packaging Information Purchase This product is shortly to be EOL&#8217;d and is therefore not recommended for new designs.
