Semtech TS30111
High Efficiency 700mA Current-Mode Synchronous Buck DC/DC Converter, 1MHz
The TS30111 is a DC/DC synchronous switching regulator with fully integrated power switches, internal compensation, and full fault protection. The switching frequency of 1MHz enables the use of small filter components resulting in minimal board space and reduced BOM costs.
Overview
Features
- Fixed output voltage choices: 1.5V, 1.8V, 2.5V, 3.3V, and 5V Adjustable version output voltage range: 0.8V to 5V
- Wide input voltage range 4.5V to 16V (18V Abs Max)
- 1MHz +/- 10% fixed switching frequency
- Continuous output current: 700mA
- High efficiency – up to 90%
- Current mode PWM control with PFM mode for improved light load efficiency
- Voltage supervisor for VOUT reported at the PG pin
- Input supply under voltage lockout
- Soft start for controlled startup with no overshoot
- Full protection for over-current, over-temperature, and VOUT over-voltage
- Less than 10uA in standby mode
- Low external component count
Applications
- On-card switching regulators
- Set-top box, DVD, LCD, LED supply
