Low Voltage Input (7V) 89% Efficiency Adjustable Output Voltage Internal Short Circuit Protection Over-Temperature Protection On/Off Control (Ground Off)
The PT6120 series is a low voltage input (typically 7V) version of Power Trends’ high-performance 1A, 12 pin SIP Integrated Switching
Regulators (ISRs). These ISRs are designed with premium low threshold FETs for those applications requiring very low input/output voltage differentials such as battery powered equipment. This highperformance ISR family offers a unique combination of features combining 89% typical efficiency with open-collector on/ off control and adjustable output voltage. Quiescent current in the shutdown mode is less than 100µA.
