Step-Down Switching Regulator TSR 1 Series


The Tracopower TSR-1 series of step-down switching regulators are great replacement for linear regulators as they solve many power supply problems. These DC to DC converters are up to 96% more efficient with built-in capacitors and short circuit protection. Allowing full load operation up to +60°C ambient temperature without the need of any heat sink or forced cooling. The TSR-1 switching regulators provide other significant features over linear regulators. Providing better output accuracy (±2%), lower standby current of 2 mA and no requirement of external capacitors. The high efficiency and low standby power consumption makes these regulators an ideal solution for many battery powered applications.

Features & Benefits


Up to 96% efficiency
No heat-sink required
Pin compatible with LMxx linear regulators
SIP-package fits existing TO-220 footprint
Built in filter capacitors
Operation temperature range –40°C to +85°C
Short circuit protection
Wide input operating range
Excellent line / load regulation
Low standby current

Traco Power Switching Regulator, Single Output, 75mV Pk-Pk Ripple and Noise - TSR 1 Series - TSR 1-2490


Is your electronic device taking a hit from surging inputs? Drop it a step down with this switching regulator from Traco Power. It takes in 12 to 36V DC and outputs a steady 9V DC to suit your system. An efficiency rating of 95% means you can be sure it wastes minimal energy while going about its business. This means you won't need to add a heat sink to your board, freeing up space for other components. Thanks to a mean time between failures of 5,350,000h, you can count on this unit to work around the clock in demanding conditions without taking a break.

Features & Benefits


• Wide operating temperature range between -40°C and +85°C to withstand harsh environments
• Pin-compatible with LMxx linear regulators for use with legacy devices
• Low output ripple and noise of 75mV Pk-Pk for reduced electrical disturbance
• Non-conductive plastic housing shields the system from electrical hazards
• Integrated short-circuit protection helps prevent damage from current surges

Applications


• Desktop computers
• Digital cameras
• Telecommunications networks
• Medical technology

How do I mount this regulator?
