TC1303A/TC1303B/  
TC1303C/TC1304  
500 mA Synchronous Buck Regulator,  
+ 300 mA LDO with Power-Good Output  
Features  
Description  
• Dual-Output Regulator (500 mA Buck Regulator  
and 300 mA Low-Dropout Regulator)  
The  
TC1303/TC1304  
combines  
a
500 mA  
synchronous buck regulator and 300 mA Low-Dropout  
Regulator (LDO) with a power-good monitor to provide  
a highly integrated solution for devices that require  
multiple supply voltages. The unique combination of an  
integrated buck switching regulator and low-dropout  
linear regulator provides the lowest system cost for  
dual-output voltage applications that require one lower  
processor core voltage and one higher bias voltage.  
• Power-Good Output with 300 ms Delay  
• Total Device Quiescent Current = 65 µA, Typical  
• Independent Shutdown for Buck and LDO  
Outputs (TC1303)  
• Both Outputs Internally Compensated  
• Synchronous Buck Regulator:  
- Over 90% Typical Efficiency  
The 500 mA synchronous buck regulator switches at a  
fixed frequency of 2.0 MHz when the load is heavy,  
providing a low noise, small-size solution. When the  
load on the buck output is reduced to light levels, it  
changes operation to a Pulse Frequency Modulation  
(PFM) mode to minimize quiescent current draw from  
the battery. No intervention is necessary for smooth  
transition from one mode to another.  
- 2.0 MHz Fixed-Frequency PWM  
(Heavy Load)  
- Low Output Noise  
- Automatic PWM to PFM mode transition  
- Adjustable (0.8V to 4.5V) and Standard  
Fixed-Output Voltages (0.8V, 1.2V, 1.5V,  
1.8V, 2.5V, 3.3V)  
The LDO provides a 300 mA auxiliary output that  
requires a single 1 µF ceramic output capacitor,  
minimizing board area and cost. The typical dropout  
voltage for the LDO output is 137 mV for a 200 mA  
load.  
• Low-Dropout Regulator:  
- Low-Dropout Voltage = 137 mV Typical @  
200 mA  
- Standard Fixed-Output Voltages  
(1.5V, 1.8V, 2.5V, 3.3V)  
For the TC1303/TC1304, the power-good output is  
based on the regulation of the buck regulator output, the  
LDO output or the combination of both. The TC1304  
features start-up and shutdown output sequencing.  
• Power-Good Function:  
- Monitors Buck Output Function (TC1303A)  
- Monitors LDO Output Function (TC1303B)  
- Monitors Both Buck and LDO Output  
Functions (TC1303C and TC1304)  
The TC1303/TC1304 is available in either the 10-pin  
DFN or MSOP package.  
- 300 ms Delay Used for Processor Reset  
• Sequenced Startup and Shutdown (TC1304)  
• Small 10-pin 3x3 DFN or MSOP Package Options  
• Operating Junction Temperature Range:  
- -40°C to +125°C  
Additional protection features include: UVLO,  
overtemperature and overcurrent protection on both  
outputs.  
For a complete listing of TC1303/TC1304 standard  
parts, consult your Microchip representative.  
• Undervoltage Lockout (UVLO)  
• Output Short Circuit Protection  
• Overtemperature Protection  
Applications  
• Cellular Phones  
• Portable Computers  
• USB-Powered Devices  
• Handheld Medical Instruments  
• Organizers and PDAs
