PWM dimming is supported directly, which is the standard interface for display backlight controllers — the dimming ratio and low-end linearity depend on the PWM input frequency and the external inductor selection. ## 1.2 MHz switching — inductor size and ripple trade-off The 1.2 MHz switching frequency lets the designer use a small inductor (typically 4.7 µH to 10 µH range) and keeps the output ripple manageable for backlight supplies. The trade-off is slightly higher switching losses than a 500 kHz part, but the smaller footprint wins in space-constrained panel designs. The 27 V output ceiling supports up to six or seven series white LEDs, depending on their forward voltage at 35 mA.","metaTitle":"TPS61151DRCRG4 DC-DC Boost LED Driver, 27V 35mA PWM Dimming","metaDescription":"Texas Instruments TPS61151DRCRG4 DC-DC boost regulator for LED backlight. 27V output, 35mA per channel, PWM dimming, 1.2MHz switching.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Mfr":"Texas Instruments","Type":"DC DC Regulator","Series":"-","Dimming":"PWM","Package":"Tape & Reel (TR)","Topology":"Step-Up (Boost)","Frequency":"1.2MHz","Applications":"Backlight","Mounting Type":"Surface Mount","Package / Case":"10-VFDFN Exposed Pad","lifecycle_stage":"eol_hot","Voltage - Output":"27V","Number of Outputs":"2","Internal Switch(s)":"Yes","Base Product Number":"TPS61151","Operating Temperature":"-40°C~85°C(TA)","Voltage - Supply (Max)":"6V","Voltage - Supply (Min)":"2.5V","Supplier Device Package":"10-VSON (3x3)","Current - Output / Channel":"35mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$58.8000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/984d9d04c33e2276ba8ace64697cf9d3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61151DRCRG4/alternatives.json"},"ai":{"faq":[{"question":"Is TPS61151DRCRG4 obsolete or active?","answer":"There is no indication of obsolescence or a last-time-buy window."},{"question":"Does TPS61151DRCRG4 support PWM dimming?","answer":"Yes, the TPS61151DRCRG4 supports PWM dimming.
