Texas Instruments TPS60132PWPG4

Overview

TPS60132PWPG4 from Texas Instruments is a regulated 5-V, 150-mA charge pump DC-DC converter optimized for battery-powered systems operating from 2.7 V to 5.4 V input (e.g., three alkaline/NiMH cells or single Li-ion). It delivers ±4% output regulation, achieves up to 90% efficiency via adaptive 1.5×/2× mode switching, and requires only four external ceramic capacitors. It integrates low-battery detection with open-drain LBO output and supports shutdown with 0.05-µA quiescent current.

For engineers reviewing the TPS60132PWPG4 datasheet, TPS60132PWPG4 pinout, TPS60132PWPG4 application, or TPS60132PWPG4 equivalent, key selection criteria include its 150-mA output capability at 3-V input, HTSSOP-20 thermally enhanced package, integrated LBI/LBO comparator interface, pulse-skip light-load regulation, and absence of inductors for low-EMI portable power conversion.

Technical Context

The TPS60132PWPG4 implements dual single-ended charge pumps with automatic adaptive mode switching: it selects 1.5× conversion at higher input voltages (≥3.6 V) and voltage-doubling mode at lower inputs to maintain peak efficiency across 2.7–5.4 V. Its ACTIVE-CYCLE regulation uses fixed-frequency operation under heavy load and variable ON/OFF timing (pulse-skip) at light loads-enabling both low ripple and 60-µA no-load IQ.

Internally, it features a 1.21-V bandgap reference, error amplifier, high-current MOSFET switches, undervoltage lockout (1.6 V threshold), and a dedicated low-battery comparator with programmable trip (1.15–1.27 V at LBI). The LBO output is open-drain, requires external pullup to OUT, and remains high-impedance during shutdown or startup (first 500 µs invalid).

Key Specifications

Pinout & Package

TPS60132PWPG4 is housed in a thermally enhanced 20-pin HTSSOP (PWP) package measuring 6.50 mm × 4.40 mm, with exposed PowerPAD™ for improved heat dissipation (RθJC(bot) = 3.5°C/W). Four PGND pins (9,10,11,12) and dual IN/OUT paths reduce impedance and improve current handling.

Compared with TPS60130PWPG4, the TPS60132PWPG4 trades 2× output current for superior thermal performance at partial load and tighter integration of battery monitoring. Against TPS60111DGQR, it adds system-level reliability via hardware LBO alert but requires larger 20-pin footprint and additional external resistors.

FAQ

What is the maximum output current specification for the TPS60132PWPG4?

The TPS60132PWPG4 delivers a maximum continuous output current of 150 mA when supplied from a 3-V input, as confirmed in Section 7.3 (Recommended Operating Conditions) and Table 1 (Device Options) of the SLVS258B datasheet. This rating applies across the full 2.7–5.4 V input range and accounts for thermal limits in the HTSSOP-20 package.

Does the TPS60132PWPG4 support low-battery detection, and how is it configured?

Yes, the TPS60132PWPG4 integrates a low-battery detector with dedicated LBI (pin 18) and LBO (pin 17) terminals. The internal comparator trips at 1.21 V ±5%, and the battery voltage threshold is set using an external resistor divider from battery to LBI. TI recommends R1+R2 between 100 kΩ and 1 MΩ; LBO is open-drain and requires pullup to OUT.

What package type and thermal characteristics does the TPS60132PWPG4 use?

The TPS60132PWPG4 is packaged in a 20-pin HTSSOP (PWP) with PowerPAD™ thermal enhancement, measuring 6.50 mm × 4.40 mm. Its junction-to-case (bottom) thermal resistance is 3.5°C/W, and junction-to-ambient is 178.75°C/W-enabling 150 mA continuous operation in 40°C ambient with proper PCB copper pour under the exposed pad.

How does the TPS60132PWPG4 achieve high efficiency across a wide input voltage range?

The TPS60132PWPG4 uses adaptive mode switching: it automatically selects 1.5× or 2× voltage multiplication based on input voltage and load current. At higher VIN (e.g., >3.6 V), 1.5× mode reduces switching losses; at lower VIN, doubler mode ensures sufficient headroom. This architecture sustains up to 90% efficiency from 2.7 V to 5.4 V, as verified in Figures 1–4 of the datasheet.

Can the TPS60132PWPG4 be used in shutdown mode, and what is its quiescent current in that state?

Yes, asserting ENABLE (pin 3) low places the TPS60132PWPG4 into shutdown mode, disconnecting the load from the input and disabling all internal circuitry except the bandgap reference. In this state, the device draws only 0.05 µA typical (1 µA max) supply current, and output leakage remains ≤1 µA-making it ideal for long-term battery storage scenarios.
