It integrates a 3A switch, supports both analog and PWM dimming, and delivers a regulated output from 2.9V up to 38V from a supply input as low as 2.9V. ## Switching frequency range and inductor sizing The oscillator can be programmed from 200 kHz to 2.2 MHz via a single resistor. A higher frequency shrinks the inductor footprint but increases switching losses and may push the EMI peak above 1 MHz for CISPR 22 compliance. For a typical 10-LED string at 100 mA, a 22 µH inductor at 600 kHz balances efficiency and board area. The 3A switch current rating sets the practical output power ceiling. At 24 V output and 85% efficiency, the converter can deliver roughly 6 W continuous before the switch current limit is reached, which covers most medium-size LCD backlight applications. ## Dimming options: analog and PWM Both analog (DC voltage on the ADIM pin) and PWM dimming are supported. PWM dimming achieves a wider contrast ratio because the LED current is switched at full amplitude, while analog dimming avoids audible noise from the PWM frequency coupling into the output capacitor.","metaTitle":"TPS61500PWPR DC DC Regulator, Boost, 3A Switch, 14-HTSSOP","metaDescription":"Texas Instruments TPS61500PWPR step-up boost regulator with 3A internal switch, 2.9V-38V output, analog/PWM dimming.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Type":"DC DC Regulator","Series":"-","Dimming":"Analog, PWM","Package":"Tape & Reel (TR); Cut Tape (CT)","Topology":"Step-Up (Boost)","Frequency":"200kHz ~ 2.2MHz","Applications":"Backlight","Mounting Type":"Surface Mount","Package / Case":"14-TSSOP (0.173\\\", 4.40mm Width) Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Output":"2.9V ~ 38V","Number of Outputs":"1","Internal Switch(s)":"Yes","Base Product Number":"TPS61500","Operating Temperature":"-40°C~85°C(TA)","Voltage - Supply (Max)":"18V","Voltage - Supply (Min)":"2.9V","Supplier Device Package":"14-HTSSOP","Current - Output / Channel":"3A (Switch)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/85fc836aaf870e6c6ea73b499669c8c8.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61500PWPR/alternatives.json"},"ai":{"faq":[{"question":"Can TPS61500PWPR be used for multiple LEDs?","answer":"Yes, it drives multiple LEDs in a series string.
