TPSM82903
Overview
The TPSM82903 is a highly efficient, small, and flexible synchronous step-down DC-DC converter MicroSiP package module that is easy to use. A selectable switching frequency of 2.5 MHz or 1.0 MHz allows the use of small components and provides fast transient response.
- High efficiency for wide duty cycle and load range - IQ: 4-µA typical - 62-mΩ high-side and 22-mΩ low-side RDS(ON)
- 3-mm × 2.8-mm × 1.6-mm MicroSiP™ package
- Up to 3-A continuous output current
- ±0.9% feedback voltage accuracy across temp (-40°C to 125°C)
- Configurable output voltage options: - VFB external divider: 0.6 V to 5.5 V - VSET internal divider: 16 options between 0.4 V and 5.5 V
- DCS-Control topology with 100% mode
- Flexibility through MODE/S-CONF pin - 2.5-MHz or 1.0-MHz switching frequency - Forced PWM or auto (PFM) power save mode with dynamic mode change option - Automatic efficiency enhancement (AEE) - Output discharge on/off
- Highly flexible and easy to use - Optimized pinout for single-layer routing - Precise enable input - Power-good output - Adjustable soft start and tracking
- No external bootstrap capacitor required
- Create a custom design using the TPSM82903 using the WEBENCH® Power Designer
