LTC3636/LTC3636-1

Dual Channel 6A, 20V

Monolithic Synchronous

Step-Down Regulator

FEATURES

DESCRIPTION

TheLTC^®3636/LTC3636-1isahighefﬁciency,dual-channel

monolithicsynchronousbuckregulatorusingacontrolled

on-time current mode architecture, with phase lockable

switchingfrequency.Theoperatingsupplyvoltagerangeis

from 3.1V to 20V, making it suitable for lithium-ion battery

stacks as well as point of load power supply applications

from a 12V or 5V input.

Wide V Range: 3.1V to 20V

Wide V

Range:

OUT

0.6V to 5V (LTC3636)

1.8V to 12V (LTC3636-1)

Output Current per Channel: 6A

High Efﬁciency: Up to 95%

Die Temperature Monitor

Adjustable Switching Frequency: 500kHz to 4MHz

External Frequency Synchronization

Current Mode Operation for Excellent Line and

Load Transient Response

Theoperatingfrequencyisprogrammablefrom500kHzto

4MHz with an external resistor and may be synchronized

to an external clock signal. The high frequency capability

allows the use of small surface mount inductors and

capacitors. The unique constant frequency/controlled

on-time architecture is ideal for high step-down ratio ap-

plications that operate at high frequency while demanding

fast transient response.

0.6V Reference Allows Low Output Voltages

User Selectable Burst Mode^®Operation or Forced

Continuous Operation

Output Voltage Tracking and Soft-Start Capability

Short-Circuit Protected

Overvoltage Input and Overtemperature Protection

Power Good Status Outputs

Low Proﬁle 4mm × 5mm 28-Lead QFN Package

The LTC3636/LTC3636-1 can select between forced con-

tinuous mode and high efﬁciency Burst Mode operation.

The LTC3636 and LTC3636-1 differ in their output voltage

sense range.
