Texas Instruments TPS60213DGSR

Overview

TPS60213DGSR from Texas Instruments is a regulated 3.3-V charge-pump DC/DC converter for battery-powered systems, delivering up to 50 mA continuous output current from a 1.6-V to 3.6-V input, featuring power-good detection, <2 µA snooze-mode quiescent current, and <5 mV_PP output ripple using push-pull topology. It enables compact, inductorless power supply design in medical glucose meters and portable audio devices.

For engineers reviewing the TPS60213DGSR datasheet, TPS60213DGSR pinout, TPS60213DGSR application, or TPS60213DGSR equivalent, key selection criteria include its 50-mA output capability, power-good (PG) open-drain output, 10-pin MSOP (DGS) package, ultra-low 2-µA snooze current, and compatibility with ceramic flying capacitors for EMI-sensitive designs.

Technical Context

The TPS60213DGSR implements a dual single-ended charge-pump architecture operating in push-pull mode (180° phase shift), enabling continuous charge transfer to minimize output voltage ripple. Its regulation uses linskip control-seamlessly transitioning between constant-frequency linear-regulation (>7 mA load) and pulse-skip mode (<7 mA) to optimize efficiency and noise.

It integrates a power-good detector (PG) that asserts high when output reaches ≥91% of 3.3 V, with hysteresis and open-drain output requiring external pullup. The SNOOZE pin configures three modes: low (2-µA snooze, 2-mA max load), high (internal oscillator, 200–400 kHz), or clocked (synchronized to 400–800 kHz external signal).

Key Specifications

Pinout & Package

FAQ

What is the maximum continuous output current of the TPS60213DGSR?

The TPS60213DGSR delivers a guaranteed minimum of 50 mA continuous output current when supplied from a 2-V input, maintaining 3.3 V ±4% regulation across temperature and line variations. Peak current capability rises with higher input voltage-for example, ~75 mA at 3.6 V input-per absolute maximum ratings. This makes the TPS60213DGSR well-suited for powering low-power MCUs, sensors, and display drivers in compact battery-operated devices.

Does the TPS60213DGSR include a power-good indicator?

Yes, the TPS60213DGSR integrates a dedicated open-drain power-good (PG) output that goes high-impedance during startup and asserts active-high once the regulated 3.3-V output reaches ≥91% of nominal (≈3.00 V). An external pullup resistor (100 kΩ–1 MΩ) to OUT or another compatible rail is required. The PG signal remains valid in normal and synchronized modes but is disabled in snooze mode, where PG enters high-impedance state.

How does the TPS60213DGSR achieve ultra-low quiescent current in snooze mode?

The TPS60213DGSR achieves 2 µA typical quiescent current in snooze mode by disabling all switching activity and non-essential circuitry while retaining only the voltage reference and error amplifier to maintain regulation within 3.3 V ±6%. Load current is limited to 2 mA in this state. Because 2 µA is below the self-discharge rate of most primary batteries, the TPS60213DGSR effectively extends shelf life and operational standby time in infrequently used portable equipment.

Can the TPS60213DGSR be synchronized to an external clock?

Yes, the TPS60213DGSR supports external clock synchronization via the SNOOZE pin. When an AC signal (400–800 kHz, 30–70% duty cycle) is applied, the internal charge-pump stages operate at half that frequency (200–400 kHz), allowing precise EMI harmonic placement. If the SNOOZE pin is held low for >10 µs, the device enters snooze mode regardless of clock presence-ensuring robust mode control during transient conditions.

What external components are required for basic operation of the TPS60213DGSR?

The TPS60213DGSR requires only four external ceramic capacitors: two 0.47–1 µF flying capacitors (C1, C2), one ≥2.2 µF input capacitor (Ci), and one ≥2.2 µF output capacitor (Co). All must be X5R or X7R dielectric types for stable capacitance across voltage and temperature. No inductors, diodes, or feedback resistors are needed-enabling a complete, low-EMI 3.3-V supply in under 12 mm² board area.
