DescriptionThe LM2738 regulator is a monolithic, high-
frequency, PWM step-down DC-DC converterinan8-
pin WSON or 8-pin MSOP-PowerPAD package.It
provides all the active functions for local DC-DC
conversion with fast transient response and accurate
regulationin the smallest possible PCB area.
Witha minimumof external components, the LM2738 easyto use. The abilityto drive 1.5-A loads with an
internal 250-mΩ NMOS switch using state-of-the-art
0.5-µm BiCMOS technology resultsin the best power
density available. Switching frequencyis internally set 550 kHz (LM2738Y) or 1.6 MHz (LM2738X),
allowing the useof extremely small surface-mount
inductors and chip capacitors. Even though the
operating frequencies are very high, efficiencies upto
90% are easyto achieve. External enableis included,
featuring an ultralow standby currentof 400 nA. The
LM2738 utilizes current-mode control and internal
compensationto provide high-performance regulation
overa wide rangeof operating conditions. Additional
features include internal soft-start circuitryto reduce
in-rush current, cycle-by-cycle current limit, thermal
shutdown, and output over-voltage protection.
