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.
