1 Overview
This module family is a 6 MHz (2.8 V version – 3 MHz), 600 mA step-down DC to DC converter, that delivers a
fixed output from an input voltage supply of 2.3 V to 5.5 V. Using a proprietary architecture with synchronous
rectification, the P80xx is capable of delivering a peak efficiency up to 92%, while maintaining efficiency over
80% at load currents as low as 1 mA.
The Pulse Width Modulation (PWM) modulator can be synchronized to an external frequency source. At
moderate and light loads, Pulse Frequency Modulation (PFM) is used to operate the device in Power-Save
Mode with a typical quiescent current of 24 µA. Even with such a low quiescent current, the part exhibits
excellent transient response during large load swings.
At higher loads, the system automatically switches to fixed-frequency control, operating at 6 MHz. In Shutdown
Mode, the supply current drops below 1 µA, reducing power consumption. For applications that require
minimum ripple or fixed frequency, PFM Mode can be disabled using the MODE pin.

All signals are referenced to this pin.
Output voltage.
Regulated voltage output.
Enable.
The device is in Shutdown Mode when voltage to this pin is
< 0.4 V and enabled when > 1.2 V. Do not leave this pin floating. Use
a logic voltage of 1.8 V to enable / disable the device.
MODE.
Logic 1 on this pin forces the IC to stay in PWM Mode. A
logic 0 allows the IC to automatically switch to PFM during light
loads. The regulator also synchronizes its switching frequency to four
times the frequency provided on this pin. Do not leave this pin
floating.
