Description
The TS30041 (1A) and TS30042 (2A) are DC/DC synchronousswitching regulators with fully integrated power switches,internal compensation, and full fault protection. The switchingfrequency of 1MHz enables the use of small ! lter componentsresulting in minimal board space and reduced BOM costs.
Features
Fixed output voltage choices: 1.5V, 1.8V, 2.5V, 3.3V, and 5V with +/- 2% output toleranceAdjustable version output voltage range: 0.9V to (VCC - 1V) with +/- 1.5% referenceWide input voltage range: 4.5V to 40V (42V Abs Max)1MHz +/- 10% fixed switching frequencyContinuous output current: 1A (TS30041), 2A (TS30042)High efficiency up to 95%Current mode PWM control with PFM mode for improved light load efficiencyVoltage supervisor for VOUT reported at the PG pinInput supply under voltage lockoutSoft start for controlled startup with no overshootFull protection for over-current, over-temperature, andUT over-voltageSYNC function on EN/SYNC pin to control switching frequencyLess than 10uA in standby modeLow external component count
Typical applications
- On-card switching regulators
- Set-top box, DVD, LCD, LED supply
- Industrial power supplies
