Linear Technology Corp. (LTC, Milpitas, CA) announced its LT1941 triple-output, monolithic, switching regulator offered in a 28-lead TSSOP package with an exposed copper bottom. Two of the regulators are step-down converters with 3 A and 2 A switches. The third regulator can be configured as a boost, inverter or SEPIC converter and has a 1.5 A switch. All three converters are synchronized to a 1.1 MHz oscillator. The two step-down converters run on opposite phases, reducing input ripple current.
With an input-voltage range of 3.5 V to 25 V, the LT1941 regulates a broad array of power sources from four-cell batteries and 5 V logic rails to unregulated wall transformers, lead-acid batteries and distributed power supplies. Each regulator generates a power good signal when its output is in regulation, easing power supply sequencing and interfacing with microcontrollers or DSPs.
The LT1941 is available from stock in a TSSOP-28E package. Pricing starts at $5.25 each in 1,000-piece quantities.
