2 AMP ADJUSTABLE POSITIVE STEP-DOWN
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.
