Texas Instruments TPS60140PWP

Overview

TPS60140PWP from Texas Instruments is a regulated 5-V ±4% charge pump voltage tripler IC for low-power battery-powered systems, delivering up to 100 mA output current from a 1.8–3.6 V input, featuring integrated low-battery warning (LBI/LBO), 65 µA quiescent current, and shutdown isolation with 0.05 µA supply current - used in two-cell alkaline/NiMH portable instruments and smart card supplies.

For engineers reviewing the TPS60140PWP datasheet, TPS60140PWP pinout, TPS60140PWP application, or TPS60140PWP equivalent, key selection criteria include input voltage range (1.8–3.6 V), regulated 5-V output tolerance (±4%), low-battery comparator adjustability, HTSSOP-20 thermal performance (R_θJA = 42 °C/W), and absence of inductors for EMI-sensitive designs.

Technical Context

The TPS60140PWP uses an improved pulse-skip topology with active-cycle control to regulate output voltage by dynamically adjusting charge-pump output resistance - reducing peak current and output ripple across the full 0–100 mA load range. It integrates a precision 1.21 V reference and error amplifier that disables switching when V_OUT ≥ 5 V, then reactivates only as needed.

Startup includes precharge limiting to 0.8 × V_IN before full switching begins, preventing inrush into empty C_OUT. The LBI input accepts an external resistive divider to set low-battery trip between 1.15–1.27 V, while open-drain LBO provides warning with 1 mA sink capability and 0.4 V low-level output.

Key Specifications

Pinout & Package

TPS60140PWP is housed in a thermally enhanced 20-pin HTSSOP (PWP) package measuring 6.5 mm × 4.4 mm with exposed power pad for improved heat dissipation (R_θJC(bot) = 1.6 °C/W). Pin functions are validated per TI SLVS273A Rev. November 2015.

FAQ

What is the minimum input voltage required for TPS60140PWP to start up and regulate?

The TPS60140PWP incorporates undervoltage lockout (UVLO) that disables operation below 1.6 V. Startup occurs when input rises above 1.8 V, and regulation is maintained down to 1.8 V input across temperature. Below 1.8 V, output voltage drops linearly with input; the device remains functional but unregulated until UVLO threshold is crossed again.

How does the low-battery warning function work on the TPS60140PWP?

The TPS60140PWP uses an internal 1.21 V reference to compare voltage applied to the LBI pin. When LBI falls below the trip threshold (adjustable via external resistor divider), the open-drain LBO pin pulls low. LBO requires an external pullup resistor (100 kΩ–1 MΩ) to OUT and sinks up to 1 mA. During startup, LBO is invalid for the first 500 µs.

Can the TPS60140PWP drive a 100-mA load continuously across its full input voltage range?

Yes - the TPS60140PWP delivers ≥100 mA continuous output current across the full 1.8–3.6 V input range at T_J ≤ 125°C. At 2.0 V input, efficiency peaks near 75% at 100 mA; at 3.6 V, efficiency exceeds 85%. Thermal design must account for P_D = (V_OUT − V_IN) × I_OUT, especially at low VIN.

What capacitor types and values are mandatory for stable operation of the TPS60140PWP?

TI specifies X5R or X7R ceramic capacitors only. Required values: C_IN = 4.7 µF, C₁/C₂ = 2.2 µF each (flying caps), C_OUT = 10 µF. All must be low-ESR (<0.1 Ω). Z5U/Y5V ceramics are prohibited due to capacitance loss at voltage/temperature - using them causes regulation failure and excessive ripple.

Is the TPS60140PWP pin-compatible with the TPS60141PWP?

No - although both use the same HTSSOP-20 (PWP) package and share most pin functions, TPS60140PWP has LBI/LBO pins (18/17), while TPS60141PWP substitutes those with NC/PG pins. Swapping them requires PCB redesign: LBI must be grounded and LBO left floating on TPS60141PWP, and PG requires external pullup. They are not drop-in replacements.
