Product introduction

LTC1702IGN 550kHz synchronous 2-phase dual switching regulator controller
(For improved current limiting, refer to the LTC1702A)

peculiarity

Two independent controllers are included in the same package
The two channels operate in different phases to minimize C_IN
All N-channel external MOSFET architectures are used
No external current sense resistor is required
Excellent Output Voltage Regulation: 1% Total Output Accuracy
Switching frequencies up to 550kHz minimize external component size
Output current per channel is 1A to 25A
High efficiency over a wide load current range
Quiescent current is reduced to less than 100μA in shutdown
Small 24-pin small and narrow SSOP package

Typical applications

description

LTC^®Ideal for low input voltage and high efficiency dual switching regulators, the 1702 contains two complete, independent switching regulators, each driving an external N-channel MOSFET in a voltage-based feedback synchronous step-down fashion. The LTC1702 operates at 550kHz using fixed frequency true pulse-width modulation (PWM) switching, minimizing external component size, cost, and load transient performance. When the output load decreases, this synchronous buck structure automatically enters intermittent operation and then into Burst Mode^®Burst operation to ensure maximum efficiency over a wide load current range.

The LTC1702 features an internal reference trimmed to 0.5% to enable converter output voltage regulation better than 1%, an open-drain logic output to indicate whether the output voltage of either channel has risen to within 5% of the final output voltage, and an optional latch FAULT to protect the load if the output voltage rises above 15% of the expected voltage. Each channel can be individually gated; When both channels are disabled simultaneously, the LTC1702 shuts down and the supply current drops below 100μA.
