Description
The TS30041 (1A) and TS30042 (2A) are DC/DC synchronous switching regulators with fully integrated power switches, internal compensation, and full fault protection. The switching frequency of 1MHz enables the use of small ! lter components resulting 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 tolerance
• Adjustable version output voltage range: 0.9V to (VCC -
1V) with +/- 1.5% reference
• Wide input voltage range: 4.5V to 40V (42V Abs Max)
• 1MHz +/- 10% ! xed switching frequency
• Continuous output current: 1A (TS30041), 2A (TS30042)
• High e" ciency up to 95%
• Current mode PWM control with PFM mode for improved
light load e" ciency
• Voltage supervisor for VOUT reported at the Power Good
(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
• SYNC function on EN/SYNC pin to control switching frequency
• Less than 10uA in standby mode
• Low external component count
Applications
• On-card switching regulators
• Set-top box, DVD, LCD, LED supply
• Industrial power supplies
