Product details
Overview
TPS60200 from Texas Instruments is a regulated 3.3 V, 100-mA charge pump DC/DC converter for low-power battery-operated systems. It operates from 1.6 V to 3.6 V input, delivers ≤5 mVPP output ripple via push-pull topology, and integrates a low-battery detector (LBI/LBO) with 1.18 V threshold. Used in MP3 players and handheld medical instruments where inductor-free, compact power conversion is required.
For engineers reviewing the TPS60200 datasheet, TPS60200 pinout, TPS60200 application, or TPS60200 equivalent, key selection criteria include its 100 mA regulated output at 3.3 V, ultra-low 35 µA quiescent current, 0.05 µA shutdown current, MSOP-10 package footprint, and integrated low-battery warning functionality with validated LBI/LBO interface behavior.
Technical Context
The TPS60200 uses dual single-ended charge pumps operating in 180° phase-shifted push-pull mode to sustain continuous output current transfer and minimize ripple. Regulation is achieved via error amplifier-controlled MOSFET gate drive in constant-frequency mode above 7 mA load, switching seamlessly to pulse-skip mode below that threshold.
It features an internal 1.18 V reference, auto-discharge circuitry that drains the output capacitor when disabled, and EN pin dual-functionality: logic-level enable/disable control and external clock synchronization input (400–800 kHz). The low-battery comparator is active only on TPS60200/TPS60202 variants and requires external resistor divider for trip-point adjustment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 3.3 V ±4% - tightly regulated rail for 3.3-V logic and analog subsystems across full input and load range |
| Max Output Current | 100 mA continuous - supports moderate digital loads such as microcontrollers and audio codecs |
| Input Voltage Range | 1.6 V to 3.6 V - compatible with two alkaline/NiMH cells down to end-of-life voltage |
| Output Ripple | <5 mVPP - enables noise-sensitive analog circuits without additional LC filtering |
| Quiescent Current | 35 µA typical - extends battery runtime in always-on or low-duty-cycle portable devices |
| Shutdown Current | 0.05 µA - isolates battery from load and prevents shelf-life drain during storage |
| Switching Frequency | 200–400 kHz internal / up to 800 kHz sync - avoids 455-kHz IF band while enabling EMI-controlled layout |
| Low-Battery Threshold | 1.18 V ±4% at LBI - precise, temperature-stable detection point for system-level battery management |
Pinout & Package
TPS60200 is housed in a 10-pin MSOP package (3.00 mm × 3.00 mm body size), optimized for space-constrained portable designs. All pins are surface-mount, with GND on pins 1 and 2 for thermal and noise performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (LBI) | Low-battery detector input | Analog input referenced to internal 1.18 V comparator; requires external resistive divider from VIN to set trip point |
| 2, 10 (GND) | Ground reference | Dual ground connections improve thermal dissipation and reduce ground bounce in high-switching-noise environments |
| 3 (C1–) | Flying capacitor negative terminal | Return node for first flying capacitor (C1); must be low-inductance path to minimize charge loss |
| 4 (C1+) | Flying capacitor positive terminal | Charge-phase node for C1; switches between IN and OUT phases in push-pull operation |
| 5 (OUT) | Regulated 3.3 V output | Power rail for downstream circuitry; bypassed with 2.2 µF ceramic capacitor to GND per design guidelines |
| 6 (C2+) | Flying capacitor positive terminal | Charge-phase node for second flying capacitor (C2); 180° out-of-phase with C1+ for ripple cancellation |
| 7 (IN) | Input supply | Accepts 1.6–3.6 V source; requires 2.2 µF ceramic bypass capacitor directly at pin |
| 8 (C2–) | Flying capacitor negative terminal | Return node for C2; symmetric layout with C1– critical for balanced push-pull operation |
| 9 (EN) | Enable/synchronization input | Three-mode control: low = shutdown, high = internal oscillator, AC signal = external sync (400–800 kHz) |
| 10 (LBO) | Open-drain low-battery output | Active-low indicator; requires external pullup (100 kΩ–1 MΩ) to OUT or compatible rail; sinks ≥1 mA |
Key Features
| Feature | Design Value |
|---|---|
| Push-pull charge pump topology | Enables continuous current delivery and <5 mVPP ripple without inductors-ideal for EMI-sensitive portable layouts |
| Integrated low-battery detector | 1.18 V ±4% threshold with 10 mV hysteresis and <50 nA LBI input leakage-supports accurate, low-power battery monitoring |
| Auto-discharge on disable | Drains OUT capacitor to <0.5 V within 0.6 ms after EN goes low-ensures safe, predictable system power-down state |
| External clock synchronization | EN pin accepts 400–800 kHz square wave; internal switching runs at half frequency-enables deterministic EMI placement |
| Ultra-low shutdown current | 0.05 µA max with battery isolation-prevents parasitic drain during long-term storage or standby modes |
| Pulse-skip + constant-frequency hybrid regulation | Seamless transition at 7 mA LinSkip threshold-maintains >90% efficiency from light to full load without manual mode selection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar regulated charge pump applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS60201DGS | Same MSOP-10 package and 3.3 V/100 mA output, but replaces LBI/LBO with PG (power-good) open-drain output; no low-battery detection capability | Suitable where system-level power sequencing or reset generation is needed instead of battery monitoring | Select TPS60201DGS only if power-good assertion (at ~90% VOUT) is required and low-battery warning is unnecessary |
| TPS60122DGS | Higher 200 mA output, same 3.3 V regulation, identical LBI/LBO function, but larger 16-pin QFN package (4×4 mm) and higher quiescent current (65 µA) | Used in more demanding portable systems needing greater current headroom and thermal margin | Choose TPS60122DGS when >100 mA sustained load or enhanced thermal performance is required; not drop-in due to pin count and footprint change |
Compared with TPS60200DGS, TPS60201DGS trades low-battery detection for power-good signaling-making it unsuitable for battery-state monitoring but appropriate for supply-rail validation. TPS60122DGS offers double the output current and same detection function but demands larger PCB area and consumes more quiescent power.

FAQ
What is the minimum input voltage supported by the TPS60200DGS?
The TPS60200DGS operates down to 1.6 V input, enabling reliable function through the full discharge curve of two alkaline or NiMH cells. At this voltage, it maintains regulated 3.3 V output up to 100 mA load, with output voltage dropping to 3.0 V minimum under worst-case conditions per datasheet Section 7.5.
How does the low-battery detection work on the TPS60200DGS?
The TPS60200DGS uses an internal 1.18 V ±4% comparator connected to the LBI pin. When voltage at LBI falls below this threshold-typically set via a resistor divider from VIN-the open-drain LBO pin pulls low. LBO requires an external pullup resistor (100 kΩ–1 MΩ) and sinks ≥1 mA when active.
Can the TPS60200DGS be synchronized to an external clock?
Yes, the TPS60200DGS accepts an external clock signal (400–800 kHz, 30–70% duty cycle) applied directly to the EN pin. Internal switching frequency becomes half the input clock frequency. If EN is held low >10 µs, the device shuts down-so clock signals must maintain valid high pulses.
What capacitors are required for basic operation of the TPS60200DGS?
The TPS60200DGS requires exactly four ceramic capacitors: 2.2 µF input (Ci), two 1 µF flying capacitors (C1, C2), and 2.2 µF output (Co). X5R or X7R dielectrics are mandatory; Z5U/Y5V types are prohibited due to capacitance loss with voltage and temperature.
Does the TPS60200DGS discharge its output capacitor when disabled?
Yes-the TPS60200DGS includes an integrated auto-discharge transistor. When EN is pulled low, the OUT capacitor discharges to <0.5 V within 0.6 ms, ensuring safe, predictable power-down behavior and eliminating residual voltage hazards in battery-powered systems.
