Rated 1.5A, these modules operate from input voltages as low as 3.1V to provide a local step-down power source. They are an ideal compliment to the industry’s latest high-performance DSPs and microprocessors. The series includes output voltage options as low as 1.0VDC. The PT5520 series is packaged in a 5-pin thermally efficient copper case. The case is solderable, has a small footprint, and can accommodate both through-hole and surface mount pin configurations. The product features external output voltage adjustment, an inhibit function, and short circuit protection. A 100µF capacitor is required for proper operation. Features • Single-Device: 5V/3.3V Input • DSP Compatible • 89% Efficiency • Small Footprint • Space-Saving package • Adjustable Output Voltage • Output Inhibit Function • Short Circuit Protection • Solderable Copper Case |
