Single Output, Non-Isolated, 5V
DC converters that accept a 5V input (4.5V to 5.5V input range) and deliver
0.8V, 1V, 1.2V, 1.5V, 1.8V, 2V, 2.5V, or 3.3V outputs at 10 Amps. LSM D5
SMT's are designed to take on-board 5V power and convert it, with the
highest efficiency in the smallest space, to any lower voltage required by
today's current-hungry DSP's, ASIC's and CPLD's.
load power processing. They occupy a mere 0.7 square inches (4.5 cm
and are only 0.34 inches (8.64 mm) high. The SMT package is designed
for pick and place including lead free reflow soldering, and they typically
require no additional external components.
chronous, fixed-frequency (300kHz), buck topology that also delivers: high
efficiency (95% for 3.3V
load regulation (±0.1%/±0.25% max.), quick step response (100μsec),
stable no-load operation, and no output reverse conduction.
tinuous short-circuit and over-temperature protection, an output-voltage
trim function, a remote on/off control pin (pull low to disable), and a sense
pin. High efficiency enables the LSM D5's to deliver rated output currents
of 10 Amps at ambient temperatures to +71°C with no air flow (natural
convection).
of inefficient linear regulators impractical, take a look at one of DATEL's
easy-to-use, low-cost LSM SMT's (or equivalent LSN SIP's). All devices
are UL/IEC/EN60950 certified and EMC compliant. UL, CB, HALT and
EMC reports are available upon request.
