Description

TPS61033DRLR is TI’s compact, high-efficiency DC-DC switching regulator (boost converter) in an 8-pin DRLR package. It’s designed for battery-powered portable electronics that need to boost a low input voltage (e.g., from a single cell) to a higher, stable output.
Key points
- Wide input range suited for Li‑ion and other low-voltage sources
- Output voltage is adjustable via feedback resistors (or available fixed options)
- High efficiency with low quiescent current; suitable for small, power-sensitive devices
- Integrated switch with protection features: overcurrent/short-circuit protection and thermal shutdown
- Enable/shutdown control for power management
- Small DRLR 8-pin package, ideal for compact boards
Typical applications
- Wearables and portable instruments
- Battery-powered sensors and MCU subsystems
- LED backlighting or indicator LEDs
For exact electrical specs, operating modes, and application examples, refer to TI’s TPS61033DRLR datasheet and product pages.

Features

TPS61033DRLR features (concise):
- Step-up (boost) DC-DC converter for battery-powered apps
- Fixed 3.3 V output
- Input voltage range: suitable for low-battery to battery-powered sources (roughly 0.9–5.5 V)
- 1.2 MHz switching frequency
- High efficiency across loads (typical high-90s % range depending on conditions)
- Enable (shutdown) control
- Soft-start to limit inrush
- Overcurrent/short-circuit protection and thermal shutdown
- Low quiescent current; suitable for long battery life
- Small 8-pin DRLR/VQFN package (compact footprint)
- External inductor required (boost topology)

Package

TPS61033DRLR is an 8‑pin VQFN (3 × 3 mm) package with an exposed pad; LR indicates RoHS lead‑free, tape‑and‑reel packaging.

Pinout

- Pin count: 8 pins (VSSOP-8 package, DRLR suffix).
- Function: A boost (step-up) DC-DC converter with a fixed 3.3 V output (used to generate 3.3 V from a lower input voltage; includes enable, feedback, and switching nodes).

Manufacturer

Texas Instruments (TI). TI is an American multinational technology company that designs and manufactures semiconductors and integrated circuits, particularly analog and power-management ICs.
