2 Amp Adjustable Positive Step-down

SLTS030B

Integrated Switching Regulator

(Revised 9/30/2000)

90% Efficiency Switching Regulators (ISRs) designed to Adjustable Output Voltage meet the on-board power conversion Internal Short Circuit Protection needs of battery powered or other equip- Over-Temperature Protection ment requiring high efficiency and small On/Off Control (Ground Off) size. This high performance ISR family Small SIP Footprint offers a unique combination of features Wide Input Range combining 90% typical efficiency with

open-collector on/off control and ad-

The PT6210 Series is a line of justable output voltage. Quiescent High-Performance 2 Amp, 12-Pin SIP current in the shutdown mode is typically (Single In-line Package) Integrated less than 100µA.

Notes: (1) The PT6210 Series requires a 100µF electrolytic or tantalum output capacitor for proper operation in all applications. (2) The ISR will operate to no load with reduced specifications. (3) Input voltage cannot exceed 30V when the inhibit function is used. (4) See Thermal Derating charts. (5) Consult the related application note for guidance on adjusting the output voltage.
