Product Overview
The<bold> RTQ2131B</bold> is a high-efficiency, monolithic synchronous step-down DC-DC converter that can deliver up to 1A output current from a 3V to 36V widely input supply. The RTQ2131B current-mode control with external compensation allows the transient response to be optimized over various loads and output capacitors. Cycleby-cycle current limit provides protection against shortcircuit output, and soft-start can eliminate input currentsurge during startup. Input under-voltage lockout, output under-voltage protection, over-current protection and overtemperature protection offers completely safe and smooth operation in all applied conditions.
- AEC-Q100 Grade 1 Qualified
- 3V to 36V Input Voltage Range
- Tight Switching Frequency Variation 2.1MHz ± 10% Over Operating Ambient Temperature
- Built-In Spread-Spectrum Frequency Modulation
- Current-Mode Control
- Integrated 200mΩ/160mΩ MOSFETs
- Stable with Low-ESR Ceramic Output Capacitors
- Enable Control
- Over-Temperature Protection
- Output Under-Voltage Protection with Hiccup Mode
- Adjacent Pin Short-Circuit Protection
Applications
Automotive, Consumer Electronics, Communications & Networking
