	INTEGRATED SWITCHING REGULATOR

•90% Efficiency

•Adjustable Output Voltage

•Internal Short Circuit Protection

•Over-Temperature Protection

•On/Off Control (Ground Off)

•Small SIP Footprint

•Wide Input Range

The PT6210 Series is a line of High-Performance 2 Amp, 12-Pin SIP (Single In-line Package) Integrated

Switching Regulators (ISRs) designed to meet the on-board power conversion needs of battery powered

or other equipment requiring high efficiency and small size. This high performance ISR family offers a unique combination of features combining 90% typical efficiency with open-collector on/off control and adjustable output voltage. Quiescent current in the shutdown mode is typically less than 100µA.

*ISR will operate to no load with reduced specifications.

**Input voltage cannot exceed 30V when the inhibit function is used. *** See Thermal Derating chart

Note: The PT6210 Series requires a 100µF electrolytic or tantalum output capacitor for proper operation in all applications.

Note 1: All data listed in the above graphs, except for derating data, has been developed from actual products tested at 25°C. This data is considered typical data for the ISR. Note 2: Thermal derating graphs are developed in free air convection cooling of 40-60 LFM. (See Thermal Application Notes).
