LTC1436A  
LTC1436A-PLL/LTC1437A  
High Efficiency Low Noise  
Synchronous Step-Down  
Switching Regulators

FEATURES  
DESCRIPTION  
The LTC®1436A/LTC1437A are synchronous step-down  
switching regulator controllers that drive external  
N-channel power MOSFETs in a phase lockable, fixed  
frequencyarchitecture.TheAdaptivePowerTM outputstage  
selectively drives two N-channel MOSFETs at frequencies  
up to 400kHz while reducing switching losses to maintain  
high efficiencies at low output currents.  
■
Maintains Constant Frequency at Low Output Currents  
■
Dual N-Channel MOSFET Synchronous Drive  
■
Programmable Fixed Frequency (PLL Lockable)  
■
Wide VIN Range: 3.5V to 36V Operation  
Low Minimum On-Time (≤300ns) for High  
■
Frequency, Low Duty Cycle Applications  
Very Low Dropout Operation: 99% Duty Cycle  
Low Dropout, 0.5A Linear Regulator for CPU I/O  
or Low Noise Audio Supplies  
■
■
An auxiliary 0.5A linear regulator using an external PNP  
pass device provides a low noise, low dropout voltage  
source. A secondary winding feedback control pin (SFB)  
guarantees regulation regardless of the load on the main  
output by forcing continuous operation.

Built-In Power-On Reset Timer  
Programmable Soft Start  
Low-Battery Detector  
Remote Output Voltage Sense  
Foldback Current Limiting (Optional)  
Pin Selectable Output Voltage  
An additional comparator is available for use as a low-  
batterydetector. Apower-onresettimer(POR)isincluded  
which generates a signal delayed by 65536/fCLK (300ms  
typically) after the output is within 5% of the regulated  
output voltage. Internal resistive dividers provide pin  
selectable output voltages with remote sense capability.  
Logic Controlled Micropower Shutdown: IQ < 25µA  
Output Voltages from 1.19V to 9V  
Available in 24-Lead Narrow SSOP and 28-Lead  
SSOP Packages U  
APPLICATIONS  
The operating current level is user-programmable via an  
external current sense resistor. Wide input supply range  
allows operation from 3.5V to 30V (36V maximum).
