LT8604/LT8604C

High Efficiency 42V/120mA

Synchronous Bucks

FEATURES

DESCRIPTION

The LT^®8604/LT8604C is a compact, high speed syn-

chronous monolithic step-down switching regulator that

delivers up to 120mA to the output with high efficiency

at a constant frequency, even up to 2.2MHz. It accepts

a wide input voltage range up to 42V and consumes

only 2.5µA of quiescent current when operating in Burst

Mode. Top and bottom power switches are included with

all necessary circuitry to minimize the need for external

components.

High Efficiency 2MHz Synchronous Operation

> 90% Efficiency at 50mA, 12V to 5V

OUT

Pin Selectable Forced Continuous or Burst Mode^®

Operation (LT8604C Only)

Ultralow Quiescent Current Burst Mode Operation

< 2.5µA I Regulating 24V to 3.3V

OUT

Output Ripple < 10mV

P-P

Wide Input Voltage Range: 3.2V to 42V

Fast Minimum Switch-On Time: 35ns

Adjustable (All) and Synchronizable (LT8604C

Only) Switching Frequency: 200kHz to 2.2MHz

Accurate 1V Enable Pin Threshold (All) with

Adjustable Hysteresis (LT8604C Only)

Internal Compensation

The LT8604C includes BST and INTV ceramic capaci-

tors for a more compact solution w^Ch^Cile having SYNC/

MODE and HYST pins. The SYNC/MODE pin selects the

regulator’s operation between forced continuous mode,

for predictive interference in sampling systems, Burst

Mode, for increased efficiency at light loads or spread

spectrum for Low EMI. It also allows synchronization to

an external clock to further increase signal to noise ratio

in high-resolution acquisition systems.
