2 Amp Adjustable Positive Step-down

Integrated Switching Regulator

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 equip-

ment 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 ad-

justable output voltage. Quiescent

current in the shutdown mode is typically

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.
