# TPS62840DLCR (Component) ## Description 1.8V to 6.5V, 750mA, 60nA IQ step-down converter The TPS62840 is a high-efficiency step-down converter with ultra-low operating quiescent current of typically 60 nA. The device contains special circuitry to achieve just 120 nA IQ in 100% mode to further extend battery life near the end of discharge. The device uses DCS-Control to cleanly power radios and operates with a typical switching frequency of 1.8 MHz. In Power-Save Mode, the device extends the light load efficiency down to a load current range of 1 μA and below. 16 predefined output voltages can be selected by connecting a resistor to pin VSET, making the device flexible for various applications with a minimum amount of external components. The STOP pin of the device immediately eliminates any switching noise in order to take a noise-free measurement in test and measurement systems. The TPS62840 provides an output current of up to 750 mA. With an input voltage of 1.8 V to 6.5 V, the device supports multiple power sources such as 2S to 4S Alkaline, 1S to 2S Li-MnO2 , or 1S Li-Ion/LiSOCl2 • 60-nA operating quiescent current • 100% duty-cycle mode with 120-nA IQ • Input voltage range VIN from 1.8 V to 6.5 V • Output current up to 750 mA • RF friendly DCS-Control™ • 80% efficiency at 1 µA IOUT (3.6 VIN to 1.8 VOUT) • 16 selectable output voltages via VSET pin • Auto transition PFM/PWM or forced-PWM mode • Selectable forced PWM and STOP modes • Output discharge function • 25-nA shutdown current • SON-8, WCSP-6 and thermally enhanced HVSSOP-8 packages #CommonPartsLibrary #IntegratedCircuit #PowerManagement ## Component Details - **Owner:** lcsc - **Created:** 11/5/2024 - **Last Updated:** 5/28/2026 - **Visibility:** Public - **Manufacturer Part Number:** TPS62840DLCR - **Part Type:** DC-DC Converters - **JLCPCB Part Class:** Extended Part - **Datasheet URL:** https://www.lcsc.com/datasheet/C2071859.pdf?spm=wm.sxq.inf.ggs&lcsc_vid=FlkNBAIDRQULVABfFAVZBgZVFVZYBgZSQ1NeBVIFQlExVlNRTlhaX1NSQlVfVzsOAxUeFF5JWBYZEEoKFBINSQcJGk4dAgUUFAk%3D - **LCSC Part Number:** C2071859 - **Manufacturer Name:** TI(德州仪器) - **License:** https://creativecommons.org/licenses/by/4.0/ - **Package or Case Code:** VSON-8_L2.0-W1.5-P0.50-BL - **Symbol Style:** parametric-v1 - **Used in:** 250 projects ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
