Philips HTS5110 - PT6311 IC Specification

• 87% Efficiency
• Adjustable Output Voltage
• Internal Short Circuit Protection
• Over-Temperature Protection
• On/Off Control (Ground Off)
• Small SIP Footprint
• Wide Input Range
The PT6310 series is a High-
Performance 2 Amp, 12-Pin SIP
(Single In-line Package) Integrated
Switching Regulator (ISR) designed to
meet the on-board power conversion
needs of battery powered or other equip-
ment requiring high efficiency and
small size. This high perfomance ISR
offers a unique combination of features
combining 87% typical efficiency with
open-collector on/off control and ad-
justable 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.
Note:
The PT6310 requires a 100µF electrolytic or tantalum output capacitor for proper operation in all applications.
